Yes and no. Back when I first heard The Hobbit being read to me at junior school, I could imagine Middle-Earth and how it should look, then upon reading the LoTR trilogy I had in my mind what I thought it would look like. Then the LoTR movies came about… they were exactly how I imagined it. Absolutely fantastic. Hope The Hobbit is the same… !
I’m trying to think of a book I’ve read that was turned into a movie that was bad, I’m sure there have been some I just can’t think of any.
