I'd like to think I'm a fairly smart guy (when it comes to movies, not calculus or anything like that), but "Trance" eludes me. "Slumdog Millionaire" director Danny Boyle creates a puzzle in which each piece is another, smaller puzzle, and every couple of minutes, the pieces change shape, and you have to start all over again. It's a fairly exhilarating experience at first, but by the end, that exhilaration turns into exhaustion. But it's still an experience.
