Doctor Who….What?


I’m coming to the end of Downton Abbey, and so I’m looking for the next English (or, pretend English) show to watch. I’ve been hearing and seeing a lot about this Doctor Who, and judging by his name I assume that he’s supposed to remain a mystery. However, I am curious and I want to know who’s Who, what’s what and why. With several seasons in existence, from however way back when, I don’t know whether or where I should start. This short note therefore is basically a plea for advice. Is Doctor Who worth watching? If so, where should I start? If not, what else and why? Thanks!
