Too much hype

Rating: 6/10 (3 April 2012)

Two guys are chained to the floor in a bathroom with a gun and a cassette player which has instructions for escape. A bloody corpse lies in between them. It gets complicated from here. The recording tells Larry must kill Adam before he escapes or his wife and daughter will die.
They find a hacksaw in a bag but they are unable to cut the chains and contemplate cutting off their feet.
A flashbacks shows Larry lecturing students when detectives arrive to question him about his pen light being found at the scene of a jigsaw game. His wife and daughter have been kidnapped and are being watched through a mirror. A good deal of violence follows but I just did not care about any of the characters and I was bored by this horror flick.
