Big Little Lies is apparently coming back with season 3 after four years, and it should follow another HBO show’s recipe for success. Big Little Lies started out as a limited series based on Liane Moriarty's 2016 book of the same name, and the source material ended in season 1's finale, but its popularity made HBO give it a sequel, which wasn't as well-received. That said, since Nicole Kidman has recently revealed that Big Little Lies season 3 is happening, there might be a way to replicate season 1's triumph with a few changes.
