Sleepaway Camp III: Teenage Wasteland isn’t a good horror movie and honestly kind of dull, though some of the kills are at least unique (i.e. the lawnmower) but by today’s standards, and this is nothing against this film in particular, it is rather tame in all areas from sex to the violence. Even so, I guess big horror fans, and fans of the Sleepaway Camp movies specifically, might enjoy otherwise it’s a forgettable sequel.
Sleepaway Camp II: Unhappy Campers is absolutely not a very good movie but in fairness, I don’t think the filmmakers or cast thought they were making high horror art. The performances are mostly throwaways though Pamela Springsteen does make for an effective psycho, I suppose. Personally I didn’t care that much for this movie, and wasn’t that fond of the first one outside of the now well-known “twist”, but horror fanatics might treasure this sequel.
