In a crowd of horror TV shows that last for one season despite their best efforts to stand out and offer fascinating takes on horror tropes, Ryan Murphy's American Horror Stories shows no signs of slowing down. The American Horror Stories season 4 trailer suggested tales about monsters, nightmares, and darkness, and these five episodes didn't disappoint. American Horror Stories season 4, episode 3, "X" focuses on disturbing events at a hospital. The entire episode is black and white, which adds an eerie, classic, and fun tone. While the whole season is great, this particular stylish choice makes this story stand out.
