Last week was Episode 7 of this Twin Peaks reboot – approaching the halfway point for this eagerly awaited, 18-episode David Lynch-Mark Frost rematch. Among its contents was a lengthy scene in which a worker at the roadhouse sweeps up debris from the floor as the instrumental “Green Onions” plays, presumably on the jukebox. But there also were moments of more arguable import, as when Diane (Laura Dern) came face to face with the dark alter-ego version of her former boss, Kyle MacLachlan’s Dale Cooper. But until the other Cooper, fighting some sort of amnesiac rebirth as the addled Dougie, regains his composure and memory, this new Twin Peaks has no hero, and, perhaps, little point. Tonight, Episode Eight.
