Trick or treat: FX renews 'American Horror Story'

Happy Halloween from FX, which just announced the  renewal of "American Horror Story" for a second 13-episode season.

Not that there's much of a surprise element here -- according to the network, the Ryan Murphy homage to Every Horror Movie Ever Made is so far on track to be the highest-rated first season of any FX show ever, with some 4.2 million viewers a week (when you count in all the people who record and watch within seven days).

Nine new episodes remain in the current season, but if you've missed the first four, there's a Halloween marathon tonight starting at 10 (by which time any kids too young to be watching should be zoned out on chocolate).
