Query: Almost a great movie

I've read the book two times (the four of them, in fact), and I love it. The movie is faithful to the book and also most of the actors, especially Ron, Hermione, Dumbledore and Hagrid. But I have to admit that the actor who played Harry (Daniel Radcliffe) wasn't as good as I expected (altough he did look as I imagined Harry).The backgrounds where great, and they did pay atention to details and that's what makes a movie magical.In the end, I think it's a good movie, worth buying.
