“Mindcage” (**1/2 out of four) was a moderately gripping suspense thriller about a seasoned detective (Martin Lawrence) and a rookie cop (Melissa Roxburgh) who turn to an incarcerated mass murderer (John Malkovich) when a copycat serial killer is on the prowl and is terrorizing the city. Good performances and skillful filmmaking keep you guessing and watching……..until a ludicrous finale that negates much of the film and pulls the rug out from under you. Overall worth watching and may remind viewers of “Seven” and “The Silence Of The Lambs” in key scenes. Lawrence is first-rate in an unusual change-of-pace role.
