Possessed by the Night Reviews
You probably know this is a Shannon Tweed movie, so you're really wondering, "How much does she get naked?" As an added insult to the dumb story and laughable acting, her required clothes-shedding time is very limited. Her three scenes are good but all regrettably short. There is a quality bonus scene of her working out in a tiny clingy crop-top, which I cannot decide is a result of the blob's influence on her mind or the writer's inability to find a rational way to show a sweaty Shannon and he just said, "Screw it, just get on the Bowflex."
Tweed has appeared in many movies with much better stories, performances, and titillation, so leave this one until you've run through the rest.
