“Alive” (*1/2 out of four) was an overbearing horror thriller set in an abandoned sanitarium in which a man and a woman (Thomas Cocquerel and Camille Stopps) awake and find that a psychotic doctor (Angus Macfadyen) is holding them hostage and he holds the keys to their true identity and thus their survival. Seedy production design and decrepit cinematography are creepy but you’ll eventually be swallowed up and numbed by all the unpleasantness. This is what audiences get for having made “Saw” such a huge hit.
