The only episode I remember well was the one with Richard Thomas as a guy who experiments with nanotechnology and he creates these micro-robots that protect and can enhance a person's body from harm--and he injects himself with them--but they decided that he would be better off with an extra eye behind his head and when he starts to contemplate suicide they give him two more hearts and reinforce his rib cage so he can't shoot himself.
But overall--like the 80s Twilight Zone, the show felt too modern. I don't think they overshadow the originals.
