SERIES PREMIERE: Tom Perrotta’s novel, which he helped adapt for television with Damon Lindelof from Lost, is a really odd TV show to wrestle to the ground. It’s built around a fascinating and unique premise: a Rapture-type event results in the sudden disappearance of millions of people across the globe, with the focus on the people left behind to wonder why. And it’s got some excellent performances, starting with series stars Justin Theroux (pictured) and Amy Brenneman. But after watching half of this first season’s 10 episodes, I had few if any questions answered, and began to understand that most answers would never arrive. So however compelling a story line, why commit to something where the payoff may never be there? The answer to that, I guess, is a personal one, consistent with the primary subject of the series itself: It’s a question of faith. And after the brilliance of Lost was diluted by its weak and unsatisfying finale, I’m not sure, in this case, whether to count myself among the faithful.
