The teens seem credible in their roles for once. The bullying and horseplay that goes on amongst the group seems highly convincing you almost feel as though the filmmakers took their camera to a real-life summer camp and simply filmed what went on amongst the kids there. It must be said that the teens look somewhat younger than the usual ones we get in slasher films with some even barely seeming to be touching adolescence. The film is filled with bizarre characters the paedophile cook (Owen Hughes); the cooks African-American replacement (Robert Earl Jones) who keeps saying yessir to everything as though he was still a cliche from the slave era; and Mike Kellin as the camp head who covers up deaths, knowingly employs a paedophile, readily agrees to have one of the teenage girls come to his room at night, and at one point starts trying to strangle Jonathan Tierston. That the film doesnt seem too concerned about much of this ie. never condemns any of it makes it even more bizarre.
The stalking scenes are above average. There is the scene where the cook has the chair pulled from under him as he reaches in to stir a large pot, ending with the boiling water all over him. The first shot we see is a POV of his broiled arms reaching up accompanied by a screaming voice, followed by a shock cut to his burned face. There is the spooky scene where Louis Sallahan comes up into the air bubble of an overturned canoe only to be joined by someone else. When we next see him, it is his water-logged body in the canoe with a water snake crawling out of his mouth. Elsewhere we get someone locked in a toilet cubicle as a hornets nest is thrown through the window, or where Katherine Kamhi takes a shower and is stabbed through the wall.
Many modern psycho films from Psycho (1960) onwards are founded in some sort of Freudian trauma and gender-role confusion. This is something that the slasher film readily took on board. Sleepaway Camp however takes this to an extreme we even get a man-on-man sex scene at one point, which is fairly radical for the genre. This leads to one of the great endings of any slasher film. [PLOT SPOILERS] The identity of the killer is no real surprise but what is is where people come across Felissa Rose on the sand, naked and with her back to them, cradling Christopher Collets body in her lap. She stands up whereupon his severed head rolls onto the ground, before she turns around and we see her nude, covered in blood, holding a knife and that she has a dick. It is one of the great shock images of the slasher cycle. The film abruptly ends on a freeze frame of the image of her standing there no confrontation with and despatch of the killer as you might expect which makes the shock all the more effective.
There have been three sequels:- Sleepaway Camp 2: Unhappy Campers (1988), Sleepaway Camp III: Teenage Wasteland (1989) and Sleepaway Camp IV: The Survivor (2012). Director/writer Robert Hiltzik returned with his own independent sequel Return to Sleepaway Camp (1988), the only other film he has directed. Felissa Rose also gained a following on the fan circuit for her role here and has made appearances in a number of other genre films.
