Basically, there's this old house from 1922 in which people throughout the years have died in from all the creepy demons and ghosts from within the house. There's so much mystery that keeps me intrigued every second of the show.
American Horror Story also has just the right amount of fear, gore, and psychological thrills that keep me on the edge of my seat. This is the story that has me asking questions and attempting to discuss theories of what is going on in the house. Seriously go ahead and get hooked, it's that amazing.
