I had to write a review on inception. I had to, because, it is among the BEST movies I have ever seen. Even though it does not fall in my usual definitions of best. I could say I had to do this, even though I am very much stuck for time, because, it is a movie that makes me take my "hat off and bow and kneel before and say 'that was great!'" But the real reason is what "lightning strikes everyday" says on his blog- "It is a movie that treats the audience with intellectual respect"
It is a movie that is not only intelligent, but demands an equal intelligence from the audience (not equal maybe, but at least approximately so) to appreciate it. (Of course that doesn't include people who read Wikipedia explanations or fake an understanding of the movie.) But each person individually would know how much he understood of the movie, and also that that indicates a lot about his intelligence, which was in itself a great feat!*
