This is an absolutely fantastic movie, a slow-burn drama without the idiotic ham-fisted canned emotion and forced humor that turns so many other dramas into stupidity. This has some real, nerve-jangling suspense and the terror of having to decide and act with no knowledge. True old school classic days of Hollywood quality with an original plot premise, an honest-to-god Joseph Campbell Hero's Journey, and cinematography so good it'll knock your socks off. The actors manage to convey enormous depths of emotional complexity with the tiniest of movements and expressions.
If you're a nitwit just looking for some explosions and idiots shouting drivel, pass on by, this movie is not for you. If you're looking for something smart and complex that truly speaks of the surreal union of life and death, this is the movie for you.
