The Righteous Gemstones season 4 news has already started to roll in after the third season’s conclusion, and the hit series is returning for more hilarious episodes. The HBO show follows a family of wealthy televangelists who get into all sorts of sinful trouble while trying to grow their religious empire. Mixing a humorous parody of religious grandiosity and the classic family struggles of shows such as Succession, The Righteous Gemstones is yet another example of multi-faceted comedy on HBO.
