A Real Pain is a deceptively simple film. There’s not a lot going on on the surface, but Eisenberg’s smart script and tight direction, coupled with Culkin’s firecracker performance fuel the film with heart and infectious energy. A Real Pain shines when it focuses on the cousins’ bond​​at once pained and precious—but it also works as a strong ensemble of realistic characters, and as a heartfelt tribute to the Holocaust victims of the region. Eisenberg does an excellent job of tying the characters’ flaws and emotions with the horrors of the past. It deals with heavy stuff, but there’s an impressive restraint at play here, even during Eisenberg and Culkin’s big moments. They’re moving (but never overly sentimental) and truly memorable.

Eisenberg may be the writer and director, but Culkin is the true standout. Culkin has an uncanny ability to make you tear up with the minutest movements and facial gestures. The guy’s gonna win an Oscar soon, no doubt.
