Be disturbed by the horror of a science experiment gone wrong in "The Tenant (Blu-ray)" (2010), a frightening, action-filled thriller. In an attempt to find a cure for human deformity, scientist Randy Molnar experimented on his own unborn children, his attempts at gene splicing going hideously awry in the case of his son, who arrives in the world hideously deformed, part human and part nightmare. Molnar locks the creature away in an abandoned asylum, where 25 years later Aerica D'Amaro and her fellow travelers seek shelter from the rain and find a monster on the loose.
