Yep Sleepaway Camp III is an obvious cash grab sequel that was not good. Not even fun in a bad way, or even trashy. How the same people involved with the second one made this film is sad, mostly because its look screams low, low budget. The kills are lame, the special effects are poor or non existent, and Angela is even going through the motions. By the end of the 1980s the slasher genre had run out of ideas and felt stale, and I think Sleepaway Camp III reflects that, along with other bland horror cash grabs that also failed miserably.
Oh and this film lacks good characters, has a lame plot and lacks any of the fun meta and mayhem that made the sequel good. It doesn’t have the unique weirdness of the first film, either. Even though this was supposed to be the last entry in the series, more films were made. Count me out.
