“On The Line” (** out of four) was an uneven suspense thriller about a late-night radio show host (Mel Gibson) who is alarmed when a deranged fan calls and threatens to kill the host’s family while on air unless he complies with all of his instructions and takes part in a survival game in the building of the show, leading the host to frantically try and stay alive all while trying to uncover the identity of the caller and save his family. Somewhat gripping in its setup and suspenseful midsection…………but unfortunately, film veers off the rails in its final third and takes a series of ludicrous (and irritating) plot twists that pull the rug out from under you. Gibson is rock-solid and almost makes this worth watching. A remake of the Japanese horror cult classic “Midnight FM.”
