D&D Combat on TV

Has anyone seen the last two weeks of The Walking Dead (Season Three) ?  I'm talking about the fights in the prison and the surrounding grounds.  People attempting some sort of close formation, covering each other, blocking with shields, attacking in ranks, and guys with missile weapons waiting for a clean line of fire. *THAT* is what I imagine D&D combat to be (particular in dungeons).  None of that chessboard, taking turns crap.
