SEASON PREMIERE: Last season, which was Season 1, this series seemed a little adrift as it walked through the earliest zombie outbreak in this prequel to The Walking Dead. This season, they’re adrift again, but this time it’s literal: The central group of survivors we’re following takes to the sea on a boat. Good thinking, because the dreaded Walkers can’t find them there, right? But watch out for Swimmers! For an interview with Kim Dickens (Madison), see David Hinckley's All Along the Watchtower.
