If you like that movie, watch Evil Dead.
Too pusillanimous individual
Whats the ending? (Horror movies are 2scary4me)
Copypasta'd from Wikipedia, but you probably won't understand most of this
The technicians celebrate the completion of the scenario, but a phone call informs them that Marty is still alive. Arriving at the dock, Marty saves Dana from Matthew Buckner. He reveals that he dismembered his assailant after being dragged away, stumbled upon a hidden control box, and was able to access an underground elevator. The technicians realize that Marty is immune to their drugs because one of his stashes of marijuana has not been chemically treated. Marty and Dana take the elevator down to the lower levels of the facility, passing a variety of imprisoned monsters. Dana sees Fornicus: Lord of Bondage and Pain holding an item that she remembers seeing in the cabin's cellar, and she realizes that the items in the cellar determine which monster will be released. A security team then corners her and Marty, but she uses a button in the control station called "System Purge" to release the monsters, which massacre the facility staff. Hadley, Lin, and Sitterson are killed in the carnage. Dana flees to the lower levels of the facility with Marty.
Discovering a temple adorned with large stone tablets, Dana and Marty meet the Director. They are informed that the scenario is to appease the "Ancient Ones", beings who live beneath the facility and are kept in perpetual slumber through an annual pars pro toto ritual sacrifice of five young people who embody certain archetypes: the Whore (Jules), the Athlete (Curt), the Scholar (Holden), the Fool (Marty), and the Virgin (Dana). The order in which they die does not matter, as long as the whore is first and the virgin is last, and her death is optional, as long as she suffers. Should the Ancient Ones awake, they will destroy the world. The Director reveals that rituals around the world have been taking place for the same purpose, but each of them failed. The Director urges Dana to kill Marty to complete the ritual. Dana draws a gun on Marty, but is attacked by a werewolf while the Director fights with Marty. Patience Buckner arrives and kills the Director before Marty pushes them both into the pit of an Ancient One.
