I am a die hard fan, I love the books and the movies. This movie was nice but, it was almost like a Harry Potter Paridy, it strayed from the book too much! Once you get over that and the big plot holes, then it's cute. It's nice to finally see the movie, this was not my favorite. The effects were great, it was funny, but it focused on the romance too much, a lot of inuendos!! And I agree, the screen writers add what they think should be in the books, not what is. It's like they divided the movie in half, the giddy teenagers in lust and the scrambling together of dramatic scenes. I'll just read the book if I need my Harry Potter and the Half Blood Prince fix.
