Orcas killing people? Saving whales? There was indeed a time when these issues were frontpage news and that might be the reason why this sounds like a 90s cliché to you. You might agree that this issue should be staunchly dealt with once you've watched Gabriela Cowperthwaite's 2013 documentary. Orcas still being held captive by marine parks like SeaWorld to perform stunts and to parade around swimming pools to entertain ticket-buying families. Blackfish is the story of one of them in particular: a bull Orca named Tilikum, who has killed several people as a result of their immoral imprisonment. Similar incidents tend to be covered up by the parks' operators and management. They are, however, attributable to the fact that the animals are quiet simply driven mad by the unnatural conditions they are subjected to. They are not born as killers, they are turned into them. First-hand accounts by former whale trainers and experts deliver fascinating truths about Tilikum and the species as whole, elaborating on their remarkable intelligence and social behaviors. For those unaware of this, this passionate documentary makes for a chilling watch.

It might seem like a no-brainer that trying to make a comedy movie featuring a character with cancer is not a great idea. And while there may be a good share of failed attempts in that category, 50/50 is not one of them. And then it might come as a surprise that this subtle attempt at cancer comedy comes courtesy of Superbad creators Seth Rogen and Evan Goldberg. It also stars indie cutie Joseph Gordon-Levitt as the young and fit Adam Lerner, who works as a writer for public radio before learning that he has malignant tumors all along his spine. Between his overbearing mum (Anjelica Huston), slightly obnoxious but good-hearted bestie (Seth Rogen), self-help groups, and his therapist (played by Anna Kendrick), he struggles to find a way of acquiescing to his 50/50 chance of survival. Similarly, 50/50 strikes a delicate balance between the bromance gags, the date-movie elements, and the grave subject matter at its heart. It manages to mine humor, pathos, and simple honesty from a dark situation, and is not afraid to “go there”. The result is truly compassionate comedy.

Difficult but essential viewing, Procession tracks the progress of six men undergoing art therapy—specifically, by creating short filmed scenes to process their trauma from being sexually abused by Catholic priests. The resulting films we get to see are wildly varied in the emotions they express, forming a rich and powerful tapestry of the effects abuse can leave on individuals. And to see these men confront the worst events of their lives through filmmaking begins to feel like validation for filmmaking itself, that it can truly be an art form that changes and saves lives. But even more striking, somehow, is the unbreakable bond that forms among these survivors throughout this entire process, captured with reverence and overflowing compassion by director Robert Greene.

All Quiet on the Western Front is a period epic that unflinchingly shows us the savagery and senselessness of war. Set at the tail end of World War I, it follows two main stories: that of German soldier Paul Bäumer (Felix Kammerer), whose boyish eagerness for warfare is diminished with each bloody step he takes towards the frontline, and that of Matthias Erzberger (Daniel Brühl), the real-life German politician tasked to negotiate a ceasefire between the French and German forces.

Grim and sobering, the movie will leave you nothing less than stunned after viewing. Like 1917 before it, All Quiet on the Western Front relies on the juxtaposition of raw brutality and peaceful quiet to effectively forward its anti-war message. The film is Germany’s official entry for the 2023 Academy Awards.

The film stars Jake Gyllenhaal as Lou Bloom, an impromptu freelance videographer who begins covering the crime world in LA for a local TV station. Almost as dark as a mystery can get, it is disturbing, and plays out as a combination of "Drive" and "The Network". The film is visually stunning as well as immensely suspenseful. It then becomes almost impossible to look away, even when you're the most horrified by just how far Bloom is willing to go to reach success. Gyllenhaal's performance is widely compared to that of Robert De Niro in Taxi Driver, which should give you an idea of its caliber.

Art is a hobby for most people, but for musician Jon Batiste and writer Suleika Jaouad, art is part and parcel of this thing called life. Of course, it’s part of their work, and it’s how they make a livelihood, but it’s more than that– it’s almost a spiritual ritual they cling to, especially when Jaouad finds out that her leukemia has returned. American Symphony mainly depicts the creation of said orchestral work, but director Matthew Heineman translates the symphony into cinematic form, culminating in a performance played over the intimate moments between Batiste and Jaouad. It’s not just a documentary of a performance, but a documentary about art, about creation despite life’s pains, perhaps to survive life’s pains. It’s a powerful work that makes it easy to believe in art as imperative for life, and vice versa.

This coming-of-age story based on the bestseller by the same name starts fun but veers towards darker territory. It's about a high-schooler who makes two older friends, played perfectly by Ezra Miller and Emma Watson. But as he gets closer to one of them, his anxieties and past trauma come to the surface. The impressive depth to which the makers of The Perks of Being a Wallflower were able to take it is what elevates it to greatness. It's the perfect mix between easy and challenging. If there is ever such a thing, it's this movie.

This documentary starts with Alex Lewis, who gets into a motorcycle accident and wakes up in the hospital not knowing who he is. He doesn’t remember anything (not even what a bicycle or a TV is, or who his mother or father are), but he remembers his twin brother, Marcus. When Alex gets back into his childhood home, he’s full of questions, and Marcus is full of answers. However, slowly, Marcus realizes his power to reshape Alex’s version of their past. Marcus leaves one important detail from Alex’s life that makes this documentary (as if it wasn’t already) such an insane story. I know I said it’s a sad movie, but it’s also fascinating and, ultimately, humanizing of the brothers’ experience.

Real life tragedies, especially one that's as sensationalized as the Miracle in the Andes, can be tough to depict on screen. On one hand, the film has to keep true to the story but also maintain some form of spectacle to keep people watching. Past depictions of the 1972 crash are preoccupied with the cannibalism portrayed by big name actors, but Society of the Snow takes a different route. The actors are newcomers, the threats to their lives don't require daring action stunts, and the cannibalism is limited to small chunks indistinguishable from animal meat. Instead, the spectacle of Society of the Snow is the human spirit– the vulnerability, the respect, and the generosity they've given each other in order to survive. It’s still an uncomfortable watch, especially since we get to know some of the survivors before the crash, but it’s definitely a transcendent addition to the genre dedicated to the miracle of existence.

This Oscar-nominated drama tells the story of the events leading up to the Srebrenica massacre, in which 8372 Bosnian Muslims were killed. It focuses on one U.N. worker who was caught between trying to protect her family, herself, and helping people in need.

The film is as horrific as it is relevant: up until the actual killing starts, people are constantly being assured that everything is under control and that there is no reason to panic. This gives an eerie feeling of resemblance to the tone many minorities in distress receive nowadays.

Still, Quo Vadis, Aida? stops at depicting any of the acts that were committed that day. Instead, it focuses on Aida’s unrelenting race against the clock to save whatever she can.

The key to what makes this apocalyptic thriller from Mr Robot and Homecoming showrunner Sam Esmail so unnerving is how resolute it is about not taking place in an alternate timeline. Making references to memorable events in recent history and namechecking real brands and cultural touchstones (like Tesla and Friends), Leave the World Behind is uncannily familiar — which, when combined with the film’s meticulous crafting of tension, makes it all the more unsettling.

Though taking place amidst an ambiguous national emergency, the film is largely set in one house — a claustrophobic setting that puts the characters’ self-conceits and prejudices under a microscope and forces them to confront their own impotence in an analog world. If it all sounds a bit “we live in a society,” be assured that Leave the World Behind cleverly manages to avoid the pitfalls of seeming like a bad Black Mirror ripoff by sidestepping expectations and deploying all the atmospheric tools in its arsenal. Withholding key plot and character information to increase our own paranoia means the movie always runs the risk of disappointment when explanations are finally given, but its focus on the human drama and its well-set-up ending ultimately eclipse any niggling frustrations.

There’s no easy way to talk about racism – it’s a nebulous set of ideas that shift and change and manifests in numerous ways that many people can’t even identify as racism because of how prevalent it is. But Dr. Ibram X. Kendi has been able to write down a fairly comprehensive narrative that outlines key historical moments that shaped the world’s concept of race and Blackness, and this narrative is brought to the screen through vivid animations and strategic sequencing by director Roger Ross Williams in new Netflix release Stamped from the Beginning. It’s a provocative, passionate investigation, and it’s one that should be required viewing.

Based on a true story, Darin J. Sallam’s controversial debut feature Farha is, at heart, a brutal coming-of-age film. Set in 1948, the film is about a girl who gets locked into her family’s storeroom at the start of the Nakba, the Palestinian Catastrophe. Sallam’s choice to limit most of the film’s perspective to that small storeroom is brilliant – in some ways, it echoes the surrounding discussion about the conflict. Most of what the world knows of Palestine is limited due to having to deal with censorship, lost records, and only hearing word-of-mouth stories from ancestors who just barely survived. But what we see is already too horrific to begin with. And what the film knows is the tragedy of losing your home - having to leave childhood, leave your dreams, and leave a vibrant and living culture in order to survive.

Florence Pugh broke through with her powerhouse performance here as Katherine, a young woman who is “sold” into a coldly transactional marriage with a cruel and impotent merchant in 1800s Northern England. Lady Macbeth seems to begin as one thing — a gloomy period tale of oppression and feminist rebellion — but, on the strength of Pugh’s performance, pivots into an even bleaker subversion of that initial impression, the kind we haven’t really seen before.

When her disinterested husband takes a long leave of absence to tend to some business affairs, Katherine does more than just defy his command that she stay indoors: she begins an unabashed affair with one of her husband’s gruff groomsmen (Cosmo Jarvis), who ignites in her an obsessive passion that brings out her dark side. She’ll stop at nothing to remove any obstacles in the couple’s way — but, while her initial targets are arguably quite deserving of their fate, her scheme soon implicates the innocent. The creeping revelation that all the cruelty Katherine has been subjected to has brutalized her in turn comes as a shock, but this dramatic overturning of our expectations is made chillingly real by Pugh’s fierce, unfaltering performance.
