“Law Abiding Citizen” tries to straddle the line between thriller and social commentary and stumbles like a poor man’s “Saw.”

A home invasion costs Clyde Shelton (Gerard Butler) his wife and his child. Clyde’s despair festers into rage when calculating district attorney Nick Rice (Jamie Foxx) makes a deal to settle the case.

Jump 10 years forward and Clyde instigates a bloody round of revenge. You might think it would end with the perpetrators of the crime, but he’s determined to bring down anyone involved in the legal system.

One of the plot’s key twists – just how Clyde is carrying out all these high-tech murders while behind bars – doesn’t require a suspension of disbelief, it requires someone to hit you over the head with a stick until you sustain a concussion.

Butler needs to get his career rebooted fast. Between this and the just-released-to-DVD “Gamer,” he’s in danger of becoming the next Steven Seagal.
