I used to enjoy reading, but I can't read without someone bothering me while I'm trying to read, and I completely lose my train of thought about it. Movies I suppose, haven't been able to really read a book in three years.
I'd do both. But first, i'll go with the movie, since i don't have money to buy all the books that i want to. If the story in the movie sucks, i might re-consider whether to buy the book or not. A good example is twilight. :D
