“Mauler” (*1/2 out of four) was a pretty awful horror thriller about a group of friends (Kate Noel, Breck Cuddy, Tanya Champoux, and others) who enter a creepy murder house and a $25,000 dark-web contest but soon find that there is a maniac on the loose who’s intent on killing them one-by-one on camera. Inept timewaster practically mauls the audience with terrible acting and dialogue. Incredibly- this film seems inspired by (and rips off) the even worse “Halloween: Resurrection” and “The Blair Witch Project 2.” Can’t ANYONE make an effective horror movie these days???
