The first Harry Potter film put me off even considering reading the books.
I didn't need the movies to do that. Never read any of the books, and I'll probably never will, as I just have no interest in reading them.
Me as well. And it makes my wife sooooooo mad. I will read most any kind of sci-fi or sword/sorcery book, but I won't get near Harry Potter. She made me watch the first movie and now I will never, ever read those books.
