10 Dumb Movies With Genius Plot Twists
4. "Angela" Is The Killer - Sleepaway Camp
This 1983 slasher movie would've been quickly forgotten as one of the many uninspired Friday the 13th knock-offs were it not for a shocking final plot twist which has allowed it to live on in infamy ever since.
Up until its final two minutes, Sleepaway Camp is a lousy F13 facsimile rife with terrible dialogue, worse acting, and slack filmmaking, but with its game-changing big reveal it becomes something else entirely.
The final scene not only reveals that protagonist Angela (Felissa Rose) is the killer, but that Angela in fact has a penis, having been born as Peter yet forced to live as a girl by her aunt, after the real Angela died in a boating accident years prior.
It was a totally unique twist at the time of its release and one which remains impressively shocking today, elevating an otherwise braindead horror movie into the upper echelons of the slasher sub-genre.
