Isn't that the fun in seeing a movie? Yeah, for movies that have something profound to say. If you notice, you didn't learn anything new from this; you didn't take away anything solid or real. Just that Nolan can create a shallow, very followable plot and then when the end comes, he thinks it's so mind-blowing that he can predict what you're going to think. Like, whoahhhh, man, sooo far out. What a gimic.
