The movie was great, but there were a couple of things I didn't like about it.
I didn't like all the parts where they tried to be funny way too hard. That's the stuff you expect to find in bad action movies, but it was way too cliche for this movie.
I also didn't like that Jackson wants to turn one book into three movies, just to earn more money. Adding random stuff that wasn't in the book to the movie didn't help either. Like that White Orc guy.
