Taffy Brodesser-Akner in the NYT Magazine:
It’s a compelling but tricky premise for a TV show, because the show’s central mystery may (or may not) be teased out indefinitely. Perrotta’s novel wrapped up its story after 355 pages, but a successful HBO series has to sustain several seasons of intrigue. And because it is Lindelof’s first TV project since he was a creator of “Lost,” the ABC show that famously drew out several mysteries for many seasons — only to end with resolutions that many people found, to put it mildly, unsatisfying — this may be a good time to remember how comfortable Lindelof is with the whole idea of mystery. The short answer: very, despite everything.
