Slightly disturbed and painfully shy Angela Baker is sent away to summer camp with her cousin. Not long after Angela’s arrival, things start to go horribly wrong for anyone with sinister or less than honorable intentions. —IMDb
If you do not take Sleepaway Camp seriously like many do, it is really enjoyable. If I had watched the film at the time of its release I probably would have thought it was really stupid. However, the movie is so much fun if you do not know the ending before you watch it and if you do not overthink. It is, ultimately, only supposed to be entertaining. Something amusing: so many men in short shorts!
There are movies out there in which a single image completely changes the entire context of the rest of the film. The infamous closing of this film is probably the most extreme example.
It's so laughably homerotic and schlocky that it's few surprises, particularly the notorious climax, are more impactful.
