 The film begins with some stock footage showing a shark battling, and tearing apart, an octopus (perhaps these were the monsters spoken of in the ad line).Bill Warren said "The film is so uneventful that it's puzzling as to why it was ever made...it has no possible reason for existence...there is at least one zombie in "Teenage Zombies"".He goes on to state "The film may have taken an entire week to shoot, and Carradine probably did all his work in one day."
