My wife and I both loved the movie, but I felt like the ending was lacking. It's not about the ending being positive or negative, it just didn't leave me thinking the movie had an overall message. I don't know, I would definitely watch it again on HBO or something, but it doesn't get 5 stars from me.
After hearing for the thousandth time how good this movie was, my wife and I decided to kill a couple of extra hours going to see this movie. I'm not sure why some people think it might be the best movie this year, but it was absolutely enjoyable from the beginning to the end. We were laughing throughout the entire movie, and she cried during a few parts (I really didn't think they were THAT touching, but whatever). All in all, I'd say it's absolutely worth seeing for anyone, and the CGI is so beautiful, it's definitely worth seeing on the big screen.
