Yeah, I'd say a great deal of the film's power lies in the ending. You kinda-sorta have to view the entire film to really have a good opinion of it. I know a few people who loved the first 95% of the film, then the ending came, and they just f'ing hated it. I also know a person or two who weren't blown away until the plan comes together. Crazy film. I love it, but definitely nutty in terms of the implications of the plot.
