AMERICAN HORROR STORY, Eleven, 9.30pm
THAT’D have to stay with you, encountering Santa in the living room as a little girl, pointing out the blood on his suit and asking him if he’d hurt himself, and Santa replying that it wasn’t his blood . . . and then, well, let’s just say this episode’s not called Unholy Night for no reason. Ian McShane plays Santa, and we’ve probably all seen him do bad guys before, but you’ll need to brace yourself for this one.
