This film is definitely worth a watch if you like violent stand off films like Straw dogs, Assault on Precient 13 , v.f.w. And other similar films. The good guys use clever methods to fend off their attackers. Acting was fair to good . Tension builds nicely. This film is a good candidate for a remake and update. The leader of the villain is portrayed well as an ice cold killer. Runtime is sufficient. The films appeal is the tension and violent deaths,, and it is real life horror that could happen. The score is well done and creepy. The film held my interest from start to finish.. I liked it and suggest you consider watching.
