Saw this on Saturday night at the Players Theater and loved it. Todd Robbins, an old Coney Island hand, explains serial killers and fake mediums, in a show co-written and directed by Teller, of Penn & Teller fame. Robbins does pulls off a few stomach-churning stunts - one with "sulfuric acid" - and recreates an old seance, a la Mina Crandon or her predecessor, the wicked Eusapia Palladino.
For people who like carnivals and spook shows and crappy horror movies, it's catnip. I've heard rumors Stephen Sondheim is a fan, too. I'm looking forward to going again.
