“Circus Kane” (*1/2 out of four) was a slavish imitation of “Saw” and “The Haunting” about a reclusive circus-master (Tim Abell) who invites a group of social media stars to his haunted house and offers a grand prize of $250,000 to anyone who can make it out alive but they soon find out this is one tough house to make it out of. Full of various death traps, gore, and terrible acting. Strictly for masochists and those who can’t wait for “Jigsaw” to come out later this Fall.
