Just came back from watching the movie, and I have to say, it was much better than the first.
Don't get me wrong, I liked the first one, but this one was much more darker and a little less fantastical. I really enjoyed the Caspian/Peter jealous rivalry as well, and didn't mind the Caspian/Susan almost relationship. It was cute, it was there, but it wasn't heart stopping or anything. Which, I think was a really good move by the writers. An overbearing romance would've taken away from the general feel of the movie.
One thing that really got to me was how much it made me LOVE Peter. Lol! I didn't really care about any of the characters in the first movie, but I absolutely fell for Peter in this one. Caspian was also cute. And I really enjoyed Ed, which was a total shift from the first movie when I HATED him.
All in all, fantastic movie for its genre. However, the CODA song annoyed the HELL out of me. It actually brought the entire movie 9 notches down in my eyes. I loved every single piece of the score except the ending song. It's not so much the song itself, its how off it was from the movie's epic nature. I didn't like that. At all.
As for the fact that Peter and Susan are never going back to Narnia, if there are any other movies, I'm not watching. :shrug:
