I watched Inception yesterday. Really cool movie, probably the best one I've seen this year. The only problem I had with it is that it felt that there wasn't enough time to explore all the ideas that they introduced. I kept expecting some big plot twists and cooler stuff to happen given the film's subject and presentation, but was underwhelmed with it by the end. They introduce all those cool characters and toy with the concept of what's real and what's not but at the end of the day they follow a straight-forward story (compared to what it could've been anyway) and most characters are pretty two dimensional.
When they said they'd be spending 10 years in the deepest level I thought they'd actually do that and start losing grip of reality some years later, but it ended up being just a few action-packed hours. When they talk about the limbo and all the crazy consequences of messing with dreams you think it's leading to something big, but nothing really bad happens and the Japanese guy just agrees to come back to reality without any real tension or reason for him dying (I guess it's some sort of punishment for him?). You have a thriller questioning what is real and what is not but the closest it gets to being that is a cheap ending shot. I'm not sure how else to explain it, but I kept expecting more and just getting something predictable (I felt the same with the Prestige).
But aside from that, it is a really engaging and fun movie. Definitely my favorite Nolan film so far.
