First and foremost: how can "part 4" of anything be an "original"? This is actually closer to the book that Gary Brandner wrote that was the basis for the first movie, but being close to the book doesn't make this movie any good.
A real sleeping pill about a woman recovering from a trauma, sent to a wilderness retreat, finding that nearly everyone there is a werewolf. Nothing happens in this entire movie, just a lot of yawning from the audience ...
This looks like it could have been a TV movie ...
1/2 a star out of ****
