I was surprised by this somewhat. I expected a brainless revenge thriller. What I got was a nicely crafted caper, a throwback, a homage, to several genre films.
The storytelling was straight to the point, almost linear. A vengeful juggernaut-The Rock-gets out of jail and seeks revenge for his murdered brother. He's as focused as a laser missile. An eclectic cast of characters are in his way. A strung-out cop out for redemption (Billy Bob Thornton), a neurotic hit-man and various unsavory people.
I thought this was nice nod to 70s style vengeance driven movies and somewhat reminiscent of Richard Stark/Donald Westlake's PARKER character (seen, in its most recent incarnation in PAYBACK, starring MEL Gibson: one man seeking revenge against fellow criminals). A man focused on his mission. The Rock is a cold-blood murder machine. Nothing heroic or even sympathetic about this guy, which makes him fascinating to watch as he runs down his list.
This movie doesn't reinvent the wheel, but it is a nice cure for the sugar coated holiday releases flooding our cinemas. A nice balance of violence, solid acting and some great music provided by THE HEAVY.
