It's a fascinating premise, and I really enjoyed parts of it. That said, it probably would've been better as an essay than a film. There was so much temporal jumping that it made Inception feel easy to keep up with. There was just a bit too much political backstabbing for my tastes. I got bored with it after awhile.
Fun idea....fun film in parts...it just doesn't all add up to a good experience, IMHO.
