Average acting, camera crew visible (twice!), horrible dialogue, Angela rapping, the same Flotsam and Jetsam album cover that was shown in Part 2, below average special effects, some nice topless moments (including Jill Terashita from the original NIGHT OF THE DEMONS!), ridiculous story that is pretty much just a series of kill scenes strung together with some boring talking scenes tossed in to pad the runtime (They even said in the extras that the lame "dream sequence" full of flashbacks was added because they were contractually obligated to turn in a 80+ minute movie and they only had 78 minutes!)
The best part about SLEEPAWAY CAMP III: TEENAGE WASTELAND (besides Jill Terashita) is when I hit "eject" on my remote control. Skip this turd and skip Part 2 also. The original is a wonderful, off-kilter 80's slasher classic, but these two sequels both blow dead dogs.
Part 1 - Sleepaway Camp (1983)
Part 2 - Sleepaway Camp II: Unhappy Campers (1988)
