This movie was long, and for those who read the book, might be disappointing. The book is much better, but I think the movie stays true to the storyline of the book in only 2 1/2 hours. This book is so dark, I don't think there was any way to make the movie better. There were enough clues in the story to pave the way for the last two movies. Good fleshing out of Draco and Snape characters.
