No plans for ringing in the New Year?  Well, AMC is running a marathon of the first half of The Walking Dead's third season which will take you into the New Year and beyond.  If you've missed out on one of 2012's best shows on TV, now's your chance to get caught up.  If you're really behind on TWD, AMC will air black and white episodes from seasons one and two starting this February.  Just remember that the neighbors you see stumbling around tomorrow morning are not necessarily the infected undead and are more than likely hungover.AMC's New Year's Eve marathon of the first half of season three of The Walking Dead starts tonight at 9PM/8c and will air all eight episodes right on through into the wee hours of the morn.  Check out the full schedule here.
