The Wonderful Maladys
It's hard to write a "101" post when there's not much info to go around. You gotta love the internets because there's already a wiki page here with a small bit of info, but not much to go on. TV Script Dude also has a positive review of the show with a sneak peek at the pilot script here.
Here's what we do know:
The Wonderful Maladys centers around a dysfunction family of 3 siblings who lost their parents when they were young. There's Alice (Sarah Michelle Gellar), the borderline alcoholic; Mary (Molly Parker), the ironically screwed-up therapist; and Neil, the eccentric. Creator, Charles Randolph has said from the beginning that the role of "Alice" was created with SMG in mind - very complimentary - and she is now one of the Executive Producers.
This dramady should be a perfect fit for Gellar who (as we know from our love of Buffy) can make us laugh and cry with the best of them. I, for one, hope this works out because the girl can act and her career, post-Buffy, has not allowed her to really show her stuff.
