I decided to start watching this on a whim, and I'm now one episode away from finishing the second season.
The show was created by, stars, and was partially written by Danny McBride and is about a wealthy family which runs an evangelical megachurch. I was initially worried it was just going to be a one-note repeat of "look at how awful these megachurch people are", and while the show has plenty of that, it also makes the main characters likeable (even the really awful people like a washed up megachurch pastor played to a tee by Walton Goggins somehow have you occasionally rooting for them) and has plots that are engaging and weird. After having recently struggled through season 2 of Severance, finding a show which introduces, expands, and importantly ties up plot points at a consistent pace is refreshing.
The show is in its forth and final season. I personally find it to be a good thing when a show is able to gracefully end rather than stretching with muddled filler seasons.
Danny McBride is a naturally charismatic kind of actor who plays crude people who should be unlikable in a way that brings you along. That helps a lot. The other two people playing his siblings have a similar energy.
The main cast are second generation in the megachurch, with John Goodman playing the founder, and as such a lot of their weirdness is tinged with good old fashioned out-of-touch-rich-people parody. And the show is parody. You often aren't supposed to agree with the main characters when they are saying or doing awful things, but ay the end of the day they eventually tend to be up against people who are worse than them, making them the only protagonists in earshot.
Danny McBride gives me strong Trailer Park Boys' Robb Wells vibes.
