I’m a sucker for documentaries about cults and over-the-top evangelists, so “The Way Down” (HBO Max, streaming) fits that bill. Especially since Remnant Fellowship Church leader Gwen Shamblin Lara looks like a Barbie crossed with the Martian spy from “Mars Attacks!” The founder of a questionable “Christian weight loss program,” her connection to the scriptures are questionable, and there are accusations of abuse within the church. But it takes a long time to get through the story, which begins with a fatal plane crash. The first three episodes come today, with two to go. 

The beloved former “Daily Show” host returns with his first new series since then, “The Problem with Jon Stewart” (Apple TV+, streaming). Like the show by his former colleague “Last Week Tonight with John Oliver,” this will be focus on a single issue, and may be more activist than actively funny. 

A less likely late night host hails from “Sesame Street” with a second season of “The Not-Too-Late Show with Elmo” (HBO Max, streaming). 

A “Flintstones” spinoff that comes 60 years after the original, “Yabba-Dabba Dinosaurs!” (HBO Max, streaming) concentrates on the adult world of Peoples and Bamm-Bamm and their own Dino. 

The singer turned UFO nut now has her own series, “Unidentified with Demi Lovato” (Peacock, streaming).

From New Zealand comes a comedy series about millennial sisters who inherit a funeral home, “Good Grief” (Sundance Now, streaming), which will make its debut Monday on IFC.
