Now I'm not one to typically watch this show, so I can't really judge comparatively, however if the rest of the series was as good as this episode it bodes terribly well for it. This is quite possibly the only episode of any show ever, that I have found so profoundly disturbing. It deals with a scientist who loses both his wife and son. At the time of their death his work is focused on a technology that allows one to remove the personality of someone and put it onto a computer. When his wife and son are caught in a car crash, he manages to get the son's mind onto a computer in time, but sadly not his wife. He then uploads the sons mind onto a robot torso, essentially reincarnating the son to an extent. This is where it turns unfortunately, as things begin to go awry.
The scientist begins to upgrade the boys chassis in order to give him more freedom, but the limitations and risks involved result in some incredibly powerful scenes that provide much food for thought in this field. I shan't give away any more as the rest would involve spoilers, but I have honestly never seen something so disturbing, yet intrinsically fascinating since. Well worth watching.
