I may have seen this film once before, but I didn't remember much about it. This movie has some good parts, but much like the rest of them, is very different from the book and somehow manages to be 2 and a half hours and leave out a good part of the book too. I like some of the later films more, actually, because Harry, Hermione, and Ron are all more developed as people. Here, you barely scratch the surface at who they are, though there are some moving scenes, and some of the graphics are nice.
I am glad that I decided to re-watch it, and I'll probably watch some of the other ones too, but I think the movies are vastly inferior to the books. They do have a great cast, and I think so much more could have been done. Somehow, they fall a bit short, though on their own, they're entertaining enough. I do really like the scene with the Mirror of Erised.
