Just the opposite for me. I love the books. I have never seen the movies and never will. While I have trouble with some of JK's writing, at times the characters seem whiny, I find the writing rich and captivating.
I hate that so many good books have been made into films. Why read when you can watch? No wonder kids don't read much anymore... they don't have to. Sooner or later the book that they would have read becomes a movie.
