I LOVE AHS. I've watched every episode of every season. The first season had some mediocre episodes. De, you should DEFINITELY finish the series. I love how they parallel reality with it. One of my favorite episodes is when they bring the Black Dahlia Murder victim (Elizabeth Short) into the story. They had her character down to a 'T' (having bad teeth, seeking fame, etc). Very interesting stuff. I love the continuous nods to Amityville Horror. However, my favorite season hands down was the second. It has demonic possessions, aliens, Nazi experiments, a bizarre love triangle, a nun combating her faith, humanoid cannibals. What more can a horror fan ask for? Plus Charlie Clouser (Saw, Dead Silence, ex-Nine Inch Nails) does the score.
Season 3 was only good in the beginning, then it turned into The Craft. It was kinda lame. I'm really looking forward to this upcoming season though. American Horror Story: Freak Show. I'm actually quite surprised no one but Akasha likes it.
