I thought the movie was brilliant. I watched it last week and wanted to comment on it while it was still fresh in my mind but I didn't have the time. The acting was great, and I thought Gordon-Levitt was perfectly cast for this role. Christopher Nolan has really outdone himself with this film. Everyone has different taste and opinions on what is good and bad, and even though almost everyone thought the movie was great, I simply thought it was even better. IMO this movie is a 10/10. Also the score = 10/10.
I think this movie takes such great risks that it is impossible to be flawless. I left thinking there were some aspects of the film that I didn't think to highly of, for example, they spent very little time explaining how exactly they have made it possible for two people to be in the same dream, interacting with one another. But sometimes you just have to take things at face value and know that there are much bigger things going on.
As for the ending, I'm content in believing that he is back to reality with his kids. Because for me, it wasn't until the top was seen spinning on the table that there was any indication otherwise. I think Nolan did that just to leave the thought resinating in peoples minds when they left the theater. He even had the top wobble a bit to make it that much more difficult to tell. You take out the last 30 seconds of the movie and I don't think people are debating it nearly as much.
I had some other questions and comments about the film but I forgot. I'd really have to watch it again to go further into it.
It seems a lot of people are afraid to rank movies to high for whatever reason. I don't give a fuck, though. This is one of the top few movies I've seen in the past decade. And it's easy for me to say that.
