Excellent set design and cinematography, but the "single take" gimmickry didn't work for me at all. Two hours is too long to see the main character on the screen 100% of the time. Looked at my watch about 80 minutes in because it was getting boring. Much of the action was pretty "overdone" unbelievable, and I felt there wasn't really any "payoff" in the ending- it left me flat. Finally... if you don't see this movie on a big, theater screen then don't bother because the "spectacle" of it will be lost and the story/character side of this movie just isn't that good.
