“Forever Home” (* out of four) was a forever dumb horror comedy about 2 dimbulb newlyweds (Sammie Lideen and Drew Leatham) who dump all their savings into a house with a haunted past and have to enlist a psychic (Shelly Boucher) to purge the house of its horrific demons leading to all Hell breaking loose. Grating film shifts done jarringly but isn’t the least funny or scary (or even entertaining). In keeping with the title, film feels like it goes on “forever” at nearly two hours.
