I thought it would be great to have a thread on this Doctor !
I’m currently doing the latest The Collection box set and I forgot how much I loved this Doctor. I think I’ll continue with seasons 8-10 and then dive into his Big Finish audios because I think I’m becoming obsessed with this Doctor 
The bonuses really help to get attached to the people behind the show.
I really want to do the collection sets one day, I own one still (I think?) I sold a couple though due to space.
I love Three’s era so much, it was my favourite classic era and I was devastated when it ended to the point where I didn’t really enjoy the rest of classic who as much. I defo need a rewatch!
I’m excited to do more of his audios, as I’ve only done a few so far but I really like the older Jo arc!
Out of all the Classic I’ve seen, Three’s era is my absolute favourite (well, just under Six’s).
It got me into Classic, I love his character, I love his companions, I love his stories, it’s just a brilliant era!
Three is so beloved to me. Put any given Three ep on and I’ll be happy. And my collection of velvet jackets is 100% his fault <3
I’m not huge on the first two doctors (saying that Troughton is growing on me)
So 3 is where my classic era begins
Love this era so much.
Pertwee and Delgado in particular have such a cartoony dynamic about them i love so much
I haven’t seen a lot of Classic Who and the same goes for 3 but I like him from what I’ve seen so far.
When Four isn’t my favourite, it’s always Three! Pertwee’s era, as well as much of Tom’s, is my comfort Who. I love all the Doctors and show eras, but this is where my heart truly lies.
I love three, he’s one of my top three doctors usually. Just amazing, I love how he is with all of his companions
Part of my love for Third admittedly comes from information outside of the show itself, namely Jon Pertwee working with Bond creator Ian Fleming in the Naval Intelligence Division during WWII. Reading him describe what he did there, it sounds an awful lot like he was (at least in part) an inspiration for Bond himself with his love for gadgets. Between that and the Sherlock Holmes cribbing during his era, with the Master as his Moriarty, I see his era as representing a culmination of the best of British fiction, between Bond, Holmes, and Doctor Who itself.
As a character, I wish I could attempt insight into what I like about him; I just think he’s cool. The alien defender of Earth, facing off against environmental threats, and while he could whip out some Venusian aikido in a pinch, I appreciated him more as the Diplomatic Doctor. The one who would push himself and those around him to find the peaceful solution to a conflict, and be extremely saddened if it didn’t turn out that way.
His relationship with UNIT is fascinating to me too. He definitely disagrees with some of their methods, and he has some particularly Holmesian moments where he’s exasperated at being the smartest (and often most ignored) man in the room, but it’s a matter of necessity without the TARDIS. As much as this era, for the most part, went against the main drive of the show (being able to go anywhere and anywhen), it made up for that with how much character work it put in place for the Third Doctor and his companions. And yes, I’m counting the Brigadier as a companion in this case; he and Third had terrific rapport with each other.
He definitely has one of my favourite regeneration stories too in Planet Of The Spiders. Not only does it play into the hubris of his particular incarnation, it was something that was actively set up and built upon throughout his era. The clarity with which his want for knowledge would lead to his end, and realising that he really does consider Earth to be his second home, is part of the reason why I still struggle with the notion that Tenth has a tragic story to his character, as it wishes it came through as well as that did. Also, crazy showcases of vehicle chases, gadgets, and regeneration examined through Buddhism, which I think is neat.
While Eleventh will always be my Doctor, Third comes a close second. I could watch Pertwee as the Doctor in just about anything and get into it, even Dimensions In Time (okay, only the parts with him in it, granted, but point still stands).
He’s my grandfather, and I love him so much 
For real though, my actual granddad looks like Pertwee, so I loved him immediately by association. Then, of course, he turns out to be a great Doctor on top of everything else.
I’m almost finishing watching his entire run for first time ever. The only story in his era that I didn’t vibe with was ‘The Mutants’; the rest goes from ‘good’ to ‘absolutely amazing’. I liked Liz alright, even though she didn’t stay long, but I would die for Jo Grant and for Sarah Jane. I already loved Sarah from SJA and her time with Four, but really didn’t expect to like Jo as much I did. Call me the Master the way this girl charmed me completely. Heck, call me the Doctor, given that she’s the main responsible for his mellowing out from grumpy exiled alien to the guy that comes back to UNIT because he likes his friends. Oh, and the UNIT gang! Love their dynamic.
Man, I just really vibe with Three. He’s one of the ruder, more testy Doctors, especially before the life changing event that is meeting Jo Grant, but his snaps are usually directed at 1) the Brig, who can take it and sometimes deserves it, 2) the Master, who absolutely deserves it and answers in kind, and 3) random evil and/or stupid side characters, who had it coming. So, really, it’s more funny than anything else. I’m a big fan of the ‘the Doctor can drive anything, and he drives like a maniac’ trope, and they really loved just putting Pertwee in increasingly strange vehicles, didn’t they? That bit in the Sea Devils where he’s chasing the Master on a jet-ski??? Amazing. And also love his outfits, and I think they work incredibly well in establishing his personality. They’re flamboyant, but never feel like costumes, because you can tell those were exactly the clothes he should be wearing.
The amazing-ness of his relationship with the Master goes without saying. They’ve been trying to recapture that magic since then, and I don’t think any other Master/Doctor pair has quite reached their level.
I have so much more to say! But bottom line is I think he’s fab. Thanks for the Venusian Lullaby, which I find myself humming all the time.
Three is my favourite Classic Doctor (other than Eight, but he doesn’t really count). After trying and failing to get through 60’s Who I made the decision to skip forward to Three’s era, and for a while I was worried that it also wasn’t working for me (I don’t personally think Spearhead from Space is as good as people claim), but it quickly grew on me.
I love Liz, and I think the Doctor works really well with someone who at least mostly matches his intellect. I immediately fell in love with Jo, though I was a bit discouraged by how much the Doctor didn’t seem to like her and how condescending he was of her. I liked it a lot better once they became more friendly. Of course, I love Sarah, and I’d go so far as to say that I prefer her with Three than with Four.
And you can’t ignore that this is the era that brought us the Master. This exact Doctor/Master dynamic has never been replicated, and I don’t think it ever could. He was almost cartoonish back then, and at this point the Master has done too much unforgivable evil for that same rapport to really work.
To me, Pertwee’s Doctor is a true comfort Doctor in many ways. Sure he might often not rank as highly as other Doctors, but gosh, he’s just great! And at times underrated when it comes to playing off some dramatic Beats (at least I get the feeling that many glosses over that Aspect he has going for).
His Eye for Fashion still hasn’t beaten yet by any other Doctor (sorry Ncuti ), all of his Velvets and Jacket while fancy feel very ‘show-off’ and that’s EXACTLY how I want the Clothes from the Doctor to feel!
His Chemistry with Delgado, Manning, John, Courtney & Sladen is just wonderful! Especially the UNIT Family Years have something very cozy to it.
If it wasn’t for such a great Cast, I don’t know if the whole Exile Seasons had worked so well as they did.
Of course his Stories have a great Track record outside of Monster of Peladon and a few more, he really had rarely duds and those that he had were rarely really frustrating (outside of Monster). Considering you get Stories like The Green Death, Invasion of the dinosaurs, The Curse of Peladon and so on, well.. what’s not to love?
I still need to get properly through the 3DAs Ranges, but what I have listened to so far does have a great grip on Era Accuracy. And it does feel like one of the more consistent Doctor Ranges BF has currently going for them!
I do also think Three is the Point where Doctor Who (the Character) really gets his fondness for Earth. While the classic Show never did ‘Arcs’ as we know them, you can see a beautiful progression from “I want to get away from this stupid Place” to “I came back Home to say Goodbye”, which is just wonderful.
While Three will probably never find his Way in my personal Top 5, his 5 Years in the Show are filled with such a warmth cozy feeling to it, a superb Supporting Cast, some entertaining Action and of course a lot of heart. No wonder why his Era really got the Show in the big leagues again and why it continues to be a wonderful Place for many to start the Classic Show!
