American Horror Story is one of the most horrifying show that I have seen till date. And believe me, I have seen many. I have seen all seasons of this show. My personal favorite season is 3rd which revolves around the story of a coven. A coven is a group of witches. Each season of American Horror Story is based on a different subject. Season wise topics of American Horror Story is written below-
1st-A haunted house.
2nd-A mental asylum.
3rd-A coven.
4th-A freak show.
5th-A haunted hotel.
If I have to rate all the seasons in the decreasing order of my liking, I would like to go like 3>1>5>2>4.
