“Unhuman Nature” (* out of four) was a near-unwatchable horror psychodrama about a troubled F.B.I. agent (Adam Meirick) sent to the Pacific Northwest on a case that nobody else wanted but soon finds himself entangled with the locals in a deadly game that the town wants to keep secret. Dreadful story is cheap and amateurish but also sluggish and boring. Meirick also co-wrote this clunker but may have bitten off more than he can type judging by the results.
