MIDSEASON PREMIERE: Apparently, the episode nine midseason premiere of Season 4 of The Walking Dead – the one premiering tonight at 9 ET on AMC – was accidentally released early this morning (Sunday), for a few hours, on Xbox Video. (Those damned walkers – they’ll show up anywhere!) Well, for those watching on AMC, the action resumes tonight, preceded by a rerun showing of episodes from the first half of the season. And if you remember the cliffhanger (if you saw it, you should), you know there’s lots of action to resume.
