12 Most Horribly Disappointing Horror Movie Villain Reveals

After a boat crash, that killed most of her family, Angela (Felissa Rose) moves in with her aunt Martha (Desiree Gould) and her cousin Ricky (Jonathan Tiersten) eight years later.

She finds it difficult to socialise in her new environment and so she visits a summer camp and that's where strange murders happen around her as four camp visiters are found dismembered on the beach, making it clear that a serial killer is on the loose.

In the end, it is revealed that the killer is Angela's brother Peter who had been committing the crimes whilst under the delusion that he was actually his deceased sister. Wait.. what? So how was he able to kill all those people without anyone noticing him?

Granted, there is a moment near the beginning that hints Martha’s been faking the kids’ physical records but surely authorities would have noticed that Peter wasn't attending school.

Or worse, that he was attending school as his dead sister, Angela. Considering the fact that the killer was able to pose as a female for eight years is a head-scratcher that ultimately leads to a dissatisfying finish.
