If you want to get started watching Doctor Who, I'd say after the new series, this episode is the best place to jump in. There was some major retooling done for the seventh season, and this is like the start of a new show, with a new Doctor introduced gradually from the perspective of the other characters. It's also probably the highest quality of all the classic stories, with writing, acting and production values on par with (low budget) feature films of the time. The plot is almost identical to "The Invasion," but it's a good plot to steal, so I don't mind.
