Friday the 13th is a series of Slasher Movies, currently containing twelve installments (with the thirteenth in development). This Villain Based Franchise is mainly based around the hockey-masked wearing, machete-wielding, Psychopathic Manchild of a Zombie named Jason Voorhees. As a child, Jason allegedly drowned at Camp Crystal Lake due to the negligence of the teenage camp counselors. Decades later, the lake and surrounding campgrounds are rumored to be "cursed" and are the setting for a series of mass murders staged on or around Friday the 13th (Jason's birthday).
