Witch-ful thinking: 'American Horror Story' offers a new variety of scares

The new season of American Horror Story is set in a coven full of powerful witches.

American Horror Story: Coven, the third season of the FX anthology series, differs in many ways from Season Two, trading a harrowing asylum for a witches’ coven; 1960s Massachusetts for present-day New Orleans; and deep, deep darkness for scary with a dash of comedy, co-creator Ryan Murphy says.
