Seriously? I mean it seems such a waste. Not reading IT, The Shining, Carrie, The Green Mile, Misery and others just because they have been turned to movies? You will be missing so much and even if the movie is a good adaption, which isn't always the case, They almost always make small, sometimes big changes to the story. And of course the biggie: To read a book is a totally different experience than seeing a movie. You very seldom get the atmosphere, the feeling of being sucked in heads first into the story. It is like saying i've eaten the apple(movie) so now i dont need to eat the orange(book) because they are both fruits. I'm sorry for becoming unclear, the simile is not very good. By the way read the game of thrones books. They are very good. I can only assume you haven't seen the series. Otherwise you probably wouldn't need to read them.
