They tried to make one with an all homosexual male cast and then stopped after people complaining. Then they did one with an all black and I think it lasted a day. People don’t want their old, favorite shows rebooted.
TV recycles old material all the time. Magnum, The FBI, Hawaii 5-0, McGyver, Dynasty, Gossip Girl, Walker, Charmed. I haven't seen any of the reboots, but somebody out there has to be watching them.
