Under the Dome (10pm, CBS) - This Wilmington-filmed series, based on a novel by Stephen King, returns for its second season tonight, with an episode written by King. We’ll get to see what happened after the explosion of pink stars in the Season 1 finale -- and also, if Big Jim (Dean Norris) will actually let Barbie (Mike Vogel) hang. We’re guessing Barbie is safe, but King recently told reporters that he’s loving the new TV trend in which no characters are safe, and that he “jumped at the chance to kill off a couple of loved series regulars.” So don’t miss it.
