I heart Harry I truly am a fan of Harry Potter, I love the books and have enjoyed the movies. The Goblet of Fire is the best one yet (it was also my favorite book).
This movie does a great job of capturing the important elements of the book, because in 2 1/2 hours, not everything can be included. The intricacies that Rowling is great at describing in her tales are well done, including the great hall, the ball, and the tournament.
For those who have not read the books, I believe you will enjoy as well. This movie moves much faster, because the focus is not on school but on the Triwizard Tournament. My friend who has not read the books, agrees that this movie is the best yet.
The main downfall of this movie is Dumbledore, he has a lack of kindness and intuition that in the books is so key to his character.
Warning: although some children may be able to deal, some parts really are a little frightening (just to keep in mind when bringing small children)
