Since its first airing back in 1963, Doctor Who has built up a staggering repertoire of almost 900 episodes, not including spin-off shows like Torchwood and The Sarah Jane Chronicles. That’s a lot of Doctor Who to get through, but we’ve all got our favorite episodes. While I’ve been around long enough to have seen some of the older episodes, I’m not ashamed to admit that I don’t think they stand the test of time very well.
