The folks over at Bookslut aren't sure if this is horrifying or exciting:

Actor Michael Douglas is behind one of several new projects being considered for next year. He is executive producer of a drama series about the late author Shirley Jackson (The Haunting of Hill House). Described as a cross between Desperate Housewives and The Twilight Zone, the series mixes supernatural tales with Jackson's own saga, "a family drama about the unconventional life of an urban clan living in small-town Vermont," says Mark Stern, chief of original programming.

I think that it definitely falls into the 'horrifying' category. 

Shirley Jackson deserves so much more than to be turned into some ass TV show for the Sci-Fi channel.  Haven't they proved time and time again that they SUCK at stuff like this?
