Time travel is a trendy topic on TV right now. And in so many ways, we have Doctor Who and the TARDIS to thank for that. The classic sci-fi series that still has Comic-Con currency started in the early 1960s, and has (mostly) stayed on the air for every decade since. (The Doctor did take a break, save for a TV movie, in the ‘90s.) There are a ton of episodes and many, many hours to consume. Best move: Pick your favorite (or potentially favorite) doctors and work from there. 36 seasons (not counting specials), 526 hours.
