The Walking Dead returns for the second half of its fourth season February 9, and AMC has released this predictably ominous teaser. For a show that is very heavy on action, TWD finds itself doing the same things over and over: Carl? Still sweaty and dead behind the eyes. Michonne? Still swingin' that sword. Rick? Still trying to convince people to be Team Rick. Because The Walking Dead is set in the South, there's a certain quota of gravely-ness the show has to fill in both advertisements and episodes. This video meets the requirement with a really slow, spooky cover of "Bad Moon Rising."
