Yes Cruise doesn't match the Lee Childs description of the character but...Cruise is great at being enigmatic and the film is action packed and moves at a great pace with no fancy 007 or Mission impossible gadgets, just a few cracked heads.
This is a refreshingly good action film - safe bet for a Saturday night on the sofa
Basic plot - Reacher is an ex- Army police investigator and trained to deal justice in a 2 million strong force of armed soldiers who now lives a nomadic lifestyle with no possessions to slow him down.
Reachers only link to civilization is his abhorrence at injustice so he does what the rest of us only dream about...he uses his unique skill set to redress the balance and right wrongs.
if you grew up on anti-hero's such as the A-team, Zorro, batman then you'll love this film, a few dark laughs as well...watch with confidence,
