Yeah, see, that's exactly how I was feeling after watching it. I sort of had buyers' remorse as well, but I guess there are worse movies to blind-buy. It isn't like I didn't enjoy it, and like I said, it looked pretty amazing - but the story/movie itself didn't do anything for me in particular. It wasn't bad, but just nothing spectacular either. I think I notice it more because - as mentioned already - it has all this praise heaped on it non-stop, as well as the awards nominations. I don't know if it is a "younger generation" or just the hype building on its own, but I'm not quite sure why I've heard at least three people tell me it is "the best movie I've ever seen".
Like I said, I enjoyed it well enough, but I'm not so sure I'll watch it again either - at least not anytime soon (I thought it was a little too long as well). Prior to seeing this, and even now after, I really don't see this movie being "remembered" 20 years down the road like Star Wars was/is - aside from it being the largest earning picture. It just didn't seem all that revolutionary otherwise, aside from the pretty pictures.
