@Megadoomer said in Doctor Who:
When it comes to the modern series, I'll likely keep going in order, though for the classic series (1-8), I'm not sure which Doctors are worth looking into. When I finish Tom Baker's second-to-last season, I'll likely get the box set for his first one (I've heard good things about Genesis of the Daleks), but I'm not sure which of the other classic Doctors are considered highlights/good ones. (maybe Jon Pertwee?)
As I'm sure you've gathered already, Tom Baker is pretty much the quintessential Doctor of not only the classic series, but possibly the entire franchise. There are many stories throughout his seven-year career that are worth checking out, of which I would recommend The Ark in Space, Pyramids of Mars, the Brain of Morbius, The Deadly Assassin, the Robots of Death, the Talons of Weng-Chiang and especially Genesis of the Daleks.
As for the other Doctors, I'd say the 2nd, 3rd, and 7th are generally considered to have the best runs aside from Baker. Personally, I believe we've never had a "bad" Doctor, just good Doctors situated with bad stories. But here's a quick breakdown of all of them.
1st, Hartnell - For me, probably the weakest run of the classic series. Hartnell does fine, but the stories haven't aged particularly well in terms of pacing and intrigue. Also, a lot of episodes have unfortunately been lost with only the audio and still frames remaining. You could watch Unearthly Child just for the sake of watching the very first episode of the series (but you can safely skip the following three caveman episodes, which are pretty mid). The Aztecs, The Dalek Invasion of Earth, and The Romans may also be worth a look.
2nd, Troughton - Definitely an improvement from Hartnell's run, and Troughton is a lot more..."Doctory". Again, a lot of missing stories from this run, but there are still many worth checking out: The Tomb of the Cybermen, the Enemy of the World, The Web of Fear, the Mind Robber, and The War Games. Also, even though it's a missing episode, I would highly recommend Power of the Daleks. There's an animated reconstruction of it that's well worth watching.
3rd, Pertwee - Although I personally don't think there are too many strong standout episodes of Pertwee's run, this era of Doctor Who still has an undeniable charm. It shakes things up with the Doctor being stranded on Earth and working with UNIT (at least for a while) and you really get to love the group dynamic of the cast. I recommend Spearhead from Space, Inferno, Day of the Daleks, The Three Doctors, and The Time Warrior.
5th, Davison - Peter Davison is very charming, but fairly subdued as the Doctor. Plus, most of his stories just aren't that great. Still, I would recommend Castrovalva, Earthshock, Enlightenment (though that one may require watching the previous two stories) and especially Caves of Androzani, which is one of the best stories of the entire franchise.
6th, C. Baker - Considered by most to be the worst run of the classic series. Which is a shame because Colin Baker really can act and makes for a great Doctor given the chance, as the Big Finish audios have proven (that's a whole other thing should you choose to go down that road). Sadly, I have to agree the stories are mostly pretty crap. I recommend at least watching Vengeance on Varos.
7th, McCoy - I guess kind of a divisive Doctor in terms of likeabilty, but a very interesting run nonetheless. Remembrance of the Daleks is a fan-favorite, but my personal favorite has always been Greatest Show in the Galaxy. Ghost Light and Curse of Fenric are also worth a watch.
Hope this helps and that you continue to enjoy your journey through the world of Doctor Who.
