Trust me. Lost can’t “unjump the shark.” It’s over, and viewers have figured it out, which is why it’s lost 40 percent of its audience over the course of this year. The show’s central gimmick has been to lay out a mystery, leave it unresolved, then go on to layer a new one on top of an old one. There are, I think, at least 20 pieces of plot that have been left out there to rot. For you fans, they include: What happened to Michael and Walt? How did Eko’s plane from Africa end up on the island? Why did the Smoke Monster kill Eko? And on and on and on. You just can’t do this to an audience. It’s a giant con game, and eventually the people you’re trying to con get wise and turn on you with savage anger.
