If you read one book from Lee Child on Reacher, you will surely hate this fucking movie.
Tom Cruise couldn't headbutt a sidewalk if he wanted to and that is the trademark of Jack Reacher, it's a total miscast, I hated the movie, but of course wanted to see it.
Tom Cruise may play clever, like Mission Impossible, but he sure doesn´t know how to play the ´tough guy´.

They really fucked up on this one, and a good series is now lost.

My advice, stick to the books..
