1. “The Walking Dead” (100 episodes as of Sunday at 10 p.m. on AMC; it will hit 115 at the end of Season 8 and has been renewed for Season 9) • There are those who argue that this show is not as good as it once was, that it has become repetitive and overly gory. And they’d be right. But this grim tale of those who survived that zombie apocalypse and struggle to survive the evil humans who remain still attracts a huge audience. There’s no end in sight.
