If you've read the book and are hoping for the exact same story, you will be typically disappointed. But if you are ok with Hollywood tinkering to make the story work on the big screen you'll enjoy the movie. There was good action and acting. Having read the book I understood already some of the things you usually have to "figure out" during a movie, and I could see that not having read the book might leave some confused about certain events. But in the end the story develops sufficiently to keep you excited and with enough clarity so that you understand what you need to. Thumbs up.
