This movie is SOOO great!! I think it's rated R, but I really think it should be rated PG or (at least) PG-13. It's a great story and a great movie. The acting is terrific, and so is the set design. I really recommend it.
I think this movie was definitely better than the first one, no doubt about it. But I can't say it was the best movie in the Harry Potter series. I think they could have done a little more with it, but don't get me wrong: it was a good movie.
Unlike most action adventure books, this one jumps right to the chase. Haddix really knows how to write a good book. The idea is amazing, and it's one of the best books I've ever read. It deserves way more than 5 stars!!!
