Variety - Both "The Walking Dead" and "American Horror Story" can be categorized under the "horror" genre, and both are doing well ratings-wise.
It would be wrong, however, to draw comparisons between the two, inasmuch as they appear to be working for decidedly different reasons.
I LOVE American Horror Story
I need to watch the second season of The Walking Dead and start watching American Horror Story. Guess that's what winter break is for.
