“The Snarling” (* out of four) was a lusterless horror thriller set in England in which a horror film crew (Laurence Saunders, Chris Simmons, Ben Manning, and others) are invaded and mauled by a slaughtering beast whose origins are unknown. Film liberally rips off “The Howling” practically right down to its title but there isn’t even many gore and attack scenes for rabid horror fans. “The Yawning” would be a better title for this timewaster. Saunders’ funny performance is film’s sole virtue.
