An Unearthly Child

The first story in Doctor Who's history is not one of the best overall but the first episode is one of the best episodes ever, in my opinion of course. It introduces all the characters and has to explain the TARDIS to a nation of people who still don't know what Daleks are. It accomplishes this easily, and after an intriguing first twenty minutes, the unfortunate cast are whisked off to goodness knows where.

And so we get to meet the first adversaries in Doctor Who, who turn out to be a tribe of cavemen who all speak BBC English. It's their speech that is the constant reminder that this is just a small television series, and watching it now reminds us of the programme's humble beginnings. A clever but quite silly plot brings the story to it's climax and after a tiny preview of what's to come, we're left imagining what will happen next week.
