Well, I don't know exactly how much movies I've seen and how much books I've read, I don't count them. I definitely spent more time reading than watching movies. But in term of number of books vs number of movies I would say they are about even. And yet, I can't name any single movie which comes close to dozens of books in term on how they impacted me. And the movies that I feel impacted me the most are movie adaptation of books which did impact me (reading the book AND watching the movie impacts me more than just doing one, I agree with that).

Well, after thinking more there is one movie which really impacted me as much as books did, which is also adapted from a book, but I didn't read the book : Schindler's List. But it's not a fiction. And I would have to read the book to tell if the book impacts me more or less than the movie.
