Since this is for Old Telly... Certainly the 60s stories deserve a second look for anyone interested in Doctor Who. There's a lot that's overlooked, partly because the first Doctor isn't 'funny' in the same way that most of his successors were - but he really did a lot with the role, especially in the early days making him outright unlikeable to begin with and then gradually softening him. And there's the thing that with the first Doctor we know nothing about him. All we know is he has a TARDIS and where he got it from is speculation.

And then the second Doctor.... Patrick Troughton is such a joy to watch. He can switch from being in the background, listening to taking control of a situation instantly. He's possibly my favourite Doctor, just full of energy. He's essentially comic relief when he comes back for reunion episodes but he's so good at doing serious scenes, even being manipulative.

The main problem with watching the 60s stories is the amount of incomplete episodes there are. The Loose Cannon reconstructions are available on daily motion here that plug the gaps of any missing episodes (as well as the animations). It's a different age of sci-fi, and some of the stories are slow moving and boring (don't try to binge watch these stories) - but equally some really capture a mood and era that gets overlooked when we talk about Doctor Who, even hardcore fans.
