base on a joke once tell by jim wynorski . that what i have read at the end of the closing credit . well and mr. wynorski get ta have an awful sense of humour then . this film be terrible and really . i love the first two chapter of the slumber party massacre series while the third film be quite useless and but completely watchable and compare to this piece of crap . there not even a driller killer and the plot and the acting and the character and the location and the event . everything be boring and absurd and laughable . the only good reason to watch this turkey be the girl represent if this film be a porn and i think it would have work really much well . the film lack gore too represent the first scene ( the one in the tent ) could be bloody and the scene with the headless guy knock at the door last one second . some moment of slight thrill can not save a nonexistent plot . buzzy ( lunk johnson ) seem to be the only real actor here represent i find him the only bearable character in this movie . oh . there a nonsense part with brinke stevens and who perform linda in the first slumber party massacre represent the police bother her to know more detail about the killer while but what we get be only some footage from the first film . not a dialogue and neither a monologue and or anything from this still traumatize grow up girl and who force to revive the bad 30 minute of her life ( a she say ) and give u no clue at all about the murderer . watch at your own risk .
