I saw the first movie with my wife (girlfriend at the time). About 80% of the way through it we looked at each other and agreed that this movie is the most overhyped piece of crap we have ever seen. We walked out.
Every adult that said they liked the movie that I have talked to said they have read the books. Most can not get i t through their skull that the movie by itself is slow to develop and drawn out. And quite frankly it is boring. That is, unless you already know the story.
Having said that, when all the movies have been released on DVD (and no more are in the queue), I might try watching them again.
