SEASON FINALE: Finally, tonight we learn who killed Laura Palmer. And shot J.R. Ewing. And what happened to the one-armed man. Actually, we learn the true identity of the killer, or killers, of Rosie Larsen, after a two-season plot line so prolonged, and so annoying strewn with herrings of every color, that it feels like a journey made before the creation of the national highway: all back roads, detours and dead ends. I’m still watching – but except for the lead performances, I’m not enjoying it much.
