“Satan’s Servant” (* out of four) was a dismayingly cheesy and low-rent horror thriller about two teenagers (Josephine Thompson and Ethan Gomez Zahnley) who investigate the disappearance of their friend and stumble onto a satanic plot in their small-town that could spell worldwide destruction. Utterly predictable and by-the-numbers and lacking in any sense of grandeur or thrills. Yet another schlock imitation of early Spielberg (particularly “Close Encounters Of The Third Kind”) that’s a real timewaster.
