Michael Schneider Variety Editor at Large These are indeed the waning days of the scripted basic cable juggernaut. That may be a strange thing to point out when once again, the most-watched entertainment show of the just-completed 2022-2023 TV season was “Yellowstone,” the modern western that airs on Paramount Network. But “Yellowstone” is wrapping up sometime in the next year, and the only other scripted series from a basic cabler to consistently be ranked among TV’s top shows, AMC’s “The Walking Dead,” has already ended its run. “The Walking Dead,” of course, dominated the season-ender charts for years — even beating football in the 2014-2015 TV season with a whopping 13.2 rating among adults 18-49. But as basic cable is almost completely out of the original scripted series business now (unscripted hits like “Vanderpump Rules” still abound, of course), those brief halcyon days are coming to an end.
