If you hate reality-based film-making this is awful. If you hate Film Noir, this is ugly. But for me, Nolan has convinced me he is one of the most important directors out there. I was even thinking, "It must be easy to edit a movie so that it's all backwards." But it's not, it's not any easier - and he leaves you straining and watching from scene to scene, searching for the truth. Even the final revelation will affect each viewer and leaves them searching for their own "ultimate truth" according to their own experience.
Most people comment about manipulation in connection with this movie, but after watching the last scene, I'm convinced that manipulation is not the main theme at all. I don't want to spoil it for you, but the basis of unfolding backwards in time is that you are enlisted to scrutinize the film trying to discover some set of motivations behind each character's actions later in time that makes sense. If you think you would enjoy this sort of puzzle, I think you will enjoy this excellently crafted film.
