About that I agree with New York's David Edelstein: "I truly have no idea what so many people are raving about. It's as if someone went into their heads while they were sleeping and planted the idea that Inception is a visionary masterpiece and -- hold on ... Whoa! I think I get it. The movie is a metaphor for the power of delusional hype -- a metaphor for itself"
If you haven't seen Memento, see it instead. You can see Christopher Nolan trying to recapture some of that magic, but it doesn't happen.
