How do you feel about books that have been turned into movies/TV shows? Are there any that you really like? Any horrible ones? Which are your favourites?

I love reading books that have had a movie made from them, and then watching the movie and seeing what's changed! I always try and read the book first. The only exception so far is Game of Thrones, where I am watching the corresponding TV show season before reading each book.

My favourite adaptations are Harry Potter, Hunger Games, Lord of the Rings, Jurassic Park and Tomorrow When The War Began. I can't think of any terrible ones right now, but I will post when they come to me. xD

I am also looking forward to The Giver, because I liked those books. And The Maze Runner which I haven't read yet, but hope to read before seeing the movie!
