I didn't read the book and really enjoyed the movie. Afterwards I didn't felt like there was a lot that happened in the movie, but that was not important. What I really enjoyed was the epic yet reduced aesthetics and the feel that this a bigger introduction to a hole new universe that could hold a lot of great stories. I'm thrilled for the following movies, but I don't really want to wait that long. So what I will be doing is start reading the books.
