I almost stopped watching when they "Fire in the hole" the little robot. (Basically, whatever power surge they gave that kid, he was smarter afterwards. But, you didn't know that until after the kid came out of his robot coma. I was like, I don't like the adult violence on the kid even though he is a robot. Now, later in the series, a guy who doesn't like robots, made the kid (robot) unconscious ... and I'm not going to provide a spoiler.
But the last episode I watched shook me up. I even went to the show's facebook page and commented how much I liked the series.
