Gave up on this after the third episode. I would never have bothered with it in the first place, but Alan Sepinwall's enthusiastic rave on HitFix persuaded me to give it a try. In hindsight, I should have been more suspicious that his examples of equally great shows were all ones that I'm lukewarm about at best. At the same time, he didn't mention once the show that seemed to me the most obvious parallel. I'm referring to the French Les Revenants, which, curiously, also got very high praise from him when it aired on Sundance Channel. But that show, which dealt with the sudden return of deceased loved ones as opposed to their sudden disappearance, is so completely in another league, it isn't even funny.
