The Showtime revival of Twin Peaks begins in little more than a month (May 21; mark your calendars), and I advise starting to work yourself up in anticipation with plenty of time to spare. Tonight, for example, Showtime presents the original 1990 movie-length pilot of Twin Peaks, which launched with those immortal words, “She’s dead. Wrapped in plastic.” It’s more than a quarter-century since David Lynch and Mark Frost unveiled Twin Peaks to an unsuspecting and fascinated nation – and nothing on TV since has quite equaled it for originality and audacity.
