For me the show has taken a turn that I don't care for. I don't mind the Brooks/Jo "romance," the Benny is an AI (I am rooting for Benny to be a good guy), that Emily has taken a back seat to a bigger bad, but I really hate the route the bigger bad has taken. Some of the shows nuance has been lost for me.
It is weird that Helen was the first and was created seemingly more powerful even before Emily's upgrade. Why only Helen?
At the end of the day, I would prefer the big bad to be human, and the AIs simply want to live as normal as they can. Boring to most...maybe.
