This movie is everything a slasher movie should be
A group of teenagers, stuck in 1 location at night, theres a psychopath picking them off one by one with creative kills. Its shot really well, i like the location alot, an old grocery store at night makes for a perfect setting for a slasher movie imo. Dan Hicks does a fantastic job, both as the lovable boss that gets along with everyone, and as the psychopath he later becomes.
The gore is amazing in it, that scene where the guy gets his head sawed through the middle is one of the best effects i've ever seen in a slasher movie.
Imo its almost a perfect slasher movie, and definitely one of the best from the 80's that many probably don't know about.
