I loved season 1 and really enjoyed season 2. But the writing is so bad in season 3 that I'm struggling to continue watching. The individual stories are weak, the characters motivations are even weaker. It's really as if they hired first year writers that hit every single pitfall.

Characters just materialize out of nowhere just for the plot, then disappear. People kill others with no sense of consequence or political weight. It's absolutely amateurish. They also introduce a lot more characters so it becomes confusing, and after S03E04, there is still barely any connection with the plot from season 2.

I see why Calvill left.
