It's a movie that truly challenges it's viewers. It leaves you clues through out the entire thing, and presents a story that leaves you to find what it all meant for yourself. It respects the viewers intelligence. Instead of your average summer movie which just presents a story to you on a platter, with nothing buried to figure it out, more meant to be an action flick. This is something that the mind truly enjoys...
IMO it is easily the best movie of the past decade, and Christopher Nolan's best work (impressive since he's got The Prestige, Memento and The Dark Knight already under his belt).
