Television has been not-so-quietly burying the concept of "normal life" for years now. If you ever thought America was a bastion of conventionality, here's a pot-dealing mom ("Weeds"), a serial-killing brother ("Dexter"), a meth-dealing dad ("Breaking Bad"), and a ladies club of loonies ("Desperate Housewives") for your consideration. No one knows what goes on behind closed doors, our TV writers remind us, and you really should assume it's human, flawed, illegal, or just plain twisted.
Showtime's "United States of Tara" is a logical extension of this decades-long subversion of - and liberation from - "The Brady Bunch." The comedy series, premiering tomorrow at 10 p.m., is about a suburban mother and wife, Tara Gregson (Toni Collette), who has dissociative identity disorder. When stress kicks in, Tara switches into one of her three alternates - a pot-smoking teen who goes by "T," a Mrs. Cleaver type named Alice, or Butch, a gruff Vietnam vet. Off meds due to troublesome side effects, Tara now sees her life as "a multiple-personality reunion tour."
