“Beware The Boogeyman” (* out of four) was incoherent dreck about a new doctor (Elissa Dowling) at a psychiatric hospital for the criminally insane and learns of the new cases from one of the equally insane doctors (Airisa Durand) and the various nutty patients (Chynna Rae Shurts, Rollyn Stafford, and others) she is responsible for. It’s films like this that make you think “Shelter Island” maybe wasn’t quite as bad as when it first came out. By the end of this mess, viewers themselves may feel like checking into a mental institution. “Beware” is right.
