Well, there was Sliders
. It was pretty-much all AH all the time, but with varying degrees of success. and there was an adaption of the novel Fatherland that aired on HBO (or was it Showtime?), which depicted a world where the Germans had a better time of WW2.
Then, of course, there are TV show from
Popular science fiction series which ran on NBC from 1969-75 starring Kent McCord as Adam-12, a clone who must hunt-down and stop the first eleven Adams who are dangerous psycopaths due to a flawed cloning process. He is aided in his mission by the streetwise lab technician who has befrinded him (Martin Milner). The final episode where Adam-12 finally meets his creator (portrayed by Jack Webb) never aired on television and was unseen until the series was released on DVD in 2003.
I would have loved that show. But I was born in the wrong universe. In my universe, Adam-12 (Kent McCord) was an android who thought he was a man with amnesia. It wasn't until the final episode of season one that he discovers he's not human. Befriended by a world-weary, alcoholic biologist(Martin Milner), he sets out on a quest to find the truth behind the mysterious "Rampart Project" that created him. Although the series ran until '75, it really went to hell in '73 when the network introduced a comic relief character, Boxy, played by Randolph Mantooth. After that it was a pale and poorly-written shadow of its former self.
I always preferred "CHiPs", which was about a couple of L.A. motorcycle cops with experimental microchips implanted in their brains. They were equipped with high-tech motorcycles that could do all sorts of cool stuff. The comic relief was their long-suffering sergeant, Joe Getraer, and Harlan, the technician who maintained their implants.
