The Hobbit on the other hand really feels generally awful. I watched a fan-cut of it that cuts all 3 movies down to about 4 hours of content and it felt just about watchable.
>The Harry Potter movies were fabulous in my opinion because the stories were not hacked by directors who felt they knew better than the original author. I may be wrong on that but that's my understanding - that largely the Harry Potter movies are true to the script.
I think you can attribute this more to JKR being still alive and in control of her creation than well-meaning production studios / directors.
