Well I can't say in general, because on some stories, I would rather watch them on the TV/in the Cinema, than reading the books.
And I'm sorry for all the books lovers (myself too!) but some of Tolkien's books have just too harsh writing style for me. >_> I can't stand reading and reading details. I mean I can some, but at places it's a bit went beyond for my style. >_>
But again.. books are always so much more fun, so much more details (just lets not overdo.
), and free space to imagine yourself.
