This show started to get so strong into season 1 and season 2, then completely lost it for me and went full soap opera. Seems super-common for new series; they (rightfully) don't put a lot of effort into future episodes of a show that's unlikely to last beyond the first, and run out of the motivating material. In the 80's/90's sitcom this was the "have a baby" storyline; on the grittier cable series it's focus on the broken characters and lots of sex.
