Aliens are still poking around on television, though by now you'd think they'd have found what they were looking for, and God has certainly been holding His own on TV lately, what with angels and miracles and the like. But now, finally, dead people are making something of a play--or, rather, the people that dead people talk to and appear in front of and otherwise generally pester. On Saturday nights, they have their own network show, and with excellent patrons: X-Files producers, the directors of Gods and Monsters, The Shining, and The Texas Chainsaw Massacre, and even Steven Spielberg, whose DreamWorks Television is their home.
