“Insidious Inferno” (* out of four) was an insidiously awful horror thriller about a young couple (Neil Green and Stephanie Leet) who rent a cottage in a secluded village that is (what else) haunted and had a series of gruesome past murders that remain unsolved. Umpteenth rip-off of “The Amityville Horror” and also “The Haunting” with the “Insidious” title added as a crash cash-in. Whatever; film is permeated with tired cliches and looks cheap.
