I find this in a lot of Netflix shows, where the season is ostensibly building to some revelation about who the killer or mole or whoever is, but each episode plays out like it was based only on prompts from the previous ones and not according to some planned story arc. At the end you don't see everything fall into place, you learn that there was a relationship that was not alluded to in any way through the rest of the season that suddenly makes someone the killer.
