It deserves a 8.5 for several reasons

Rating: 8/10 (29 May 2013)

Good action movie with a decent overturn, nice action scenes and a story that fits well into the genre.
But with some very welcomed differences when comparing with almost all other movies, action or not.
OK, there is a romantic couple, but even though it seems they like each other, they don't stay together in the end, and thanks for that fresh air.
The hero (Reacher) kill the bad guy in the end, avoiding an annoying prosecution and any chance of Zac getting away. If this is right or wrong it's up to you, but he did what thought was right.
Reacher just used a gun in two scenes, and because it was necessary. I'm not against weapons, but I'm against movies trying to brainwash us telling we need guns almost all the time and to solve every tricky situation we might get in.
And I liked very much the scene where Reacher talk about real freedom and points out some office workers. That was nice, because usually Hollywood tries to make us believe the world we live in is a wonderland, when we know nowadays it's just the opposite.
8.5 for all these reasons.
