Occasionally I try to watch old Doctor Who, like sixties William Hartnell Doctor Who. I've yet to finish a story line. (They tended to be in twenty-minute episodes, multiple episodes adding up to a single story line.) They're...slow. And, well, very not-profound. Basically they're not made to a modern sensibility.
But I want to watch classic Doctor Who, especially when the current season has ended, to keep me busy until the next season. Buff up on my history. But how do I know which ones are worth watching?
I have discovered what sounds like sage advice! Here it is. I'm going to take the seasons and episodes this fellow recommends and watch them in chronological order. Maybe dipping into other seasons just to get a feel for what all the other doctors are like. I would also recommend watching the very first twenty-minute episode of Doctor Who, "An Unearthly Child," maybe the second episode, too, just for seeing how it all began.
Here are the episodes I'll probably look for first:
The Dalek Invasion of Earth/World's End (1964)
The Tenth Planet (1966) (some episodes missing, but I'm curious about the first regeneration)
The Tomb of the Cybermen (1967)
Doctor Who and the Silurians (1970)
The Ark in Space (1975)
The Sontaran Experiment (1975)
