The latest episode of Showtime's revival of Twin Peaks was the Black Lodge of TV. Part eight begins normally enough (for an episode of David Lynch's oddest and longest-running creation, anyway), but it evolves into something closer to an experimental film — a kind of innocence-smashing mash-up of Terence Malick's Tree of Life, Kubrick's 2001: A Space Odyssey, film noir, sci-fi, nostalgic Americana, and — most importantly — fear.
