I prefer books. They detail the story a whole lot more.

Hmm, it depends on which way I catch the story first. If I read the book then watch the movie, I tend to like the book version more. Although, the movie version may be better than the book. If I watch the movie before reading the book, why bother going back and reading the book? lol I usually don't. It's ruined.

I like to read first. Sometimes they lose alot going to film.
