After the first movie I refused to watch the others. Too much was cut out.
I've got agree with you on that. The Harry Potter movies are some of the worst ever film adaptations of a book. It kept getting worse and worse to the point where I'm no longer looking forward to the moves. The ending of Goblet of Fire with the maze really bothered me. I remember getting so hyped for that part - for all the creatures and the mist - and then, nothing...
Then again for Order of the Pheonix, I was getting all ready for the big excited grand finale... which was toned down. I hope this is what they're trying to fix when they split Deathly Hallows.
...Or they just hope to get more money by having two movie realeases
EDIT: Wait I just remembered...I like the movie version of Azkaban better than the book, and that's even my favotite book

. It's the only Harry Potter movie I own
