what seems to be a journey about a man proving he can fool the doping tests just completely changes into anti – Russian propaganda and a political melodrama. It was good until they were about to prove something only to turn it into a stupid ass propaganda

Best documentary I’ve ever seen. Seeing real events unfolding, mad characters, corruption, doping, what more could there be. Fascinating.

Great movie. Glad i didn’t read what the movie was about because that would probably have made me stray away from the movie. It really made the subject interesting and attention-catching.

As someone who wasn’t very informed on the topic of ‘doping’ I was completely immersed in this film. And then it gets even better.

A totally engrossing film, I just kept saying wow again and again as it progressed. Humor, drama, danger it’s all here.

What was a sports documentary becomes a political thriller featuring as high as some of the most powerful people in the world: Putin’s close circle. The best thing about this documentary for me was that the Russian scientist Grigory is such a fun crazy dude. You want him to be your friend in real life, and that gives another, more humane dimension to the story.
