Things turn decidedly creepy in this only mildly thrilling thriller for a college freshman (Minka Kelly, "Friday Night Lights") whose new roomie (Leighton Meester, "Gossip Girl") seems to be everything one could want in a space sharer ... at first, anyway.
As time goes on, the Meester character displays potentially dangerous, possibly even lethal tendencies. Cam Gigandet ("Burlesque") and "Titanic" alumni Billy Zane and Frances Fisher also are in the cast. DVD extras: audio commentary by director Christian E. Christiansen; deleted scenes; alternate opening. ** (PG-13: AS, P, V) (Also on Blu-ray)
