Preacher returns and Serengeti beckons, but only one includes baby elephants learning to stand

Here’s what’s happening in the world of television for Sunday, August 4. All times are Eastern.
Top pick
Preacher (AMC, 9 p.m and 10 p.m., two-hour fourth-season premiere): Now, where were we?
‘The Light Above’ is decent, and one of the show’s better season finales. It’s a relief to have things at Angelville concluded, and the final cliffhanger, with Starr holding Cassidy captive in a massive Grail fortress, is good. But a season finale can only do so much, and heading to season 4, I’m still frustrated at the direction the show has taken, and how much the odds are against it being able to self-correct. But fingers crossed, I guess.
That’s our own Zack Handlen, writing about last season’s big finish. But there’s an even bigger finish ahead, as this adaptation of Garth Ennis and Steve Dillon’s comic careens into its final season. So, what’s ahead?
