Anyone who’s more than a passing fan of Doctor Who knows that The Doctor is a Time Lord from the planet Gallifrey. Over the decades, a substantial body of continuity has built up around them. When the new series was being launched, showrunner Russell T. Davies made it pretty clear that he wanted a completely fresh start, unburdened by all of that lore. He came up with the idea of a “Time War”, where the Time Lords and the Daleks, The Doctor’s greatest enemies, would have had a war so vast that they wound up destroying each other completely.
It didn’t work.
The Daleks quickly made an appearance, followed by Gallifrey. Things kept changing – Gallifrey was destroyed, then saved, then invaded and virtually destroyed, then saved again, then destroyed again. I’ve actually lost track…. And it’s not like we’re seeing the effects of the Time War as “reality” (as far as the series is concerned) changes around us.
It’s more like they cannot decide what to do with Gallifrey and the Time Lords.
Maybe if they stepped back a bit and first asked themselves “What do the Time Lords actually do, anyway?”
