I saw HP7. I can't even fricking remember what happened in the books, so half the movie was "did this happen in the book? Did this happen in the book? I think I remember this part..." But I think they were pretty faithful to the book because everything seemed familiar.
Also watched inception. Great movie, although I think it could have been better.
See, I can't speak for others, but when I dream the laws of reality and physics bend and break. In the movie it was impossible to tell the dream world from the real world. I was expecting a movie where reality was constantly changing, because the people in the dream were aware they were dreaming so were able to manipulate their world. Think of something and it appears. Want a bridge over a river, think it into existence and it appears. The world around you warps and changes.
The scene where Ellen Paige is showing off her skills, folding the city in half and stuff is the general idea of what I'm getting at, just taken to an extreme. However, they never too that idea to the rest of the dream sequences. It was like the producers said "Yea, we have millions of dollars to make this movie but we'll make a lame ass excuse that changing the dream angers the subconscious because we don't want to spend any of our millions on special effects.
The movie had a lot of potential that I believe was wasted.
