I've mostly watched the new version of Doctor Who, and I've become interested in the "reboot" episodes. That's where the whole cast including the Doctor is new, there's a new showrunner, and a new ongoing story. What's the closest equivalent to these in the classic series? From the new series, I'd count the TV movie, Rose, The Eleventh Hour, and The Woman Who Fell To Earth. The classic series is more episodic and I don't know how the showrunners changed, or even if there were "showrunners". But I'd count the first episode itself, An Unearthly Child, and Spearhead From Space, where there's a new Doctor and a new, Earth-based premise. Anything else?
