Great on its own, overshadowed by the book

Rating: 9/10 (9 March 2014)

I'll be short. Should you watch the movie?
That largely depends on whether you've read the book it is based on. If you haven't the answer is a resounding "YES!". The movie is very good. Then you can read the books and find even more enjoyment in the story. The details differ enough that it won't feel like too much of a spoiler.
If you have read the book first, the answer gets more complicated. You could still watch the movie, but if it matters to you how closely the movie follows the story ... you risk disappointment. The movie takes some liberties that seem to annoy people who have read the book.
I fall into the first category, thus the 9/10. I've read the book immediately afterwards, getting the best of both worlds.
