Momento was also my first into to Nolan. I was 17, and I was impressed. But I was impressed in the same way that I was impressed by The Usual Suspects. That is, on first watch I thought it was really cool, but only because it was unexpected. On second watch, you realize that the movie survives on nothing but a cheap gimmick, and that if you strip away the gimmick there isn't a lick of substance behind it. The real Kaiser Soze is the little man in your mind that prevents you from seeing the forest for the trees. I like to think that I wouldn't fall for those types of cinematic pranks now that I'm not a teenager, but who knows? I'm wiser, but damn if they don't know how to capture your attention out in your neck of the woods.
