I never studied the structure of alt.history stories but I I’ve been a fan of time travel and alt.history stories since I was a kid. Doctor Who mostly. But during the “dry spell” after Dr Who was gone forever, I ate up every Time travel tv show or movie I could find. 15 years and it was going to be forever.
So awesome that the show not only got a reboot, but it’s BETTER than the original. Love it. Hope it continues on.
