Background & Significance: So the first thing I'm obligated to say is that "The Planet of the Spiders" is a regeneration story. Yes. It's the final story starring Jon Pertwee as The Doctor and in the end of this story he regenerates into Tome Baker. But more than anything what it does is bring to a close what is, arguably, the longest single-vision run on Doctor Who.
Now I know what you're thinking. Tom Baker was around for longer. So was John Nathan-Turner. But that's not the same. For these five years of Jon Pertwee, the show was guided by the same producer and script editor, overseeing the same Doctor, giving all the stories a similar tone and feel across those five years.
Between Jon Pertwee, Barry Letts, and Terrance Dicks, Doctor Who held a consistent feel throughout the five years of Pertwee. They were based on UNIT, lots of alien invasions, and kept a constant feel of adventures with Pertwee as the leading man of action. With Dicks leaving the show to return to freelance writing at the end of this story, Pertwee moving on to bigger and better things, and with Letts departing after Tom Baker's first story, "Robot", this story becomes not just the end of Pertwee, but for the end of this era of five years of mostly solid stories. And because one of the things I notice about creative types as they go on and hone their craft is that they only seem to niche closer and closer to what they want, this is the most Pertweeian, Dicksian, Lettsian story they ever did.
And really, it's one of the most wonderfully cathartic stories out there.
Because of the way television used to work, Doctor Who was structured very episodically, with each story being a one-and-done serial spread across several episodes. There weren't ongoing plot lines or mysteries. There weren't long story threads to build towards and wrap up, no "Bad Wolf" hints to seed throughout the season with promises of paying off in some big explosive finale. Hell, even the concepts of big explosive finales was barely something the show was starting to play with. All these elements would eventually grow more and more prevalent as you push Doctor Who towards something more and more modern (the 7th Doctor/Ace stuff is the most ready example because, quite frankly, it's the most modern of Doctor Who in every sense of the word), but "Planet of the Spiders" definitely defies that to give us a crazy cathartic trek that seems to capture everything great and weak about the Pertwee era.
The only thing noticeably missing from "Planet of the Spiders" is Roger Delgado's Master, who made an appearance in every story of Pertwee's second season and then recurred throughout the next two years up until "Frontier in Space". The plan, originally, was to bring him back for Pertwee's finale, which would feature a Doctor/Master team-up/adventure in which The Master sacrifices himself to save The Doctor and we find out that The Master is the id to The Doctor's ego and that they are, in fact, the same person just divided into two halves. And, okay. I'm not exactly okay with that. Granted, I'm not a huge fan of Freud, but I'm really kinda glad that they didn't end up with that as the definitive word on The Master. I mean, why does that need to be who The Master is? Why does he need to be tied to The Doctor like that forever? Why can't it just be enough that he's an evil Time Lord from The Doctor's past?
But I'm sidetracking.
Before they could do this, though, Master-actor Roger Delgado died in a car crash in Turkey before they could move on this Master finale and writers Robert Sloman and Barry Letts chucked out what they had and re-wrote an entirely story entirely, focusing on a new villain with different themes and this whole "Id/Ego Master/Doctor" thing is lost to a parallel universe and we don't have to deal with an absurd level of Freudian over-explaining of continuity. And while Delgado was a huge loss, I must admit I'm glad because knowing me and my views on Freud I woulda hated that and (quite frankly) it would have severely weakened the character of The Master.
But alas, "The Planet of the Spiders" is the end of Pertwee and it's a hell of an ending. Not as good as "War Games," but certainly one of the best final stories a team could ask for.
So let's get to it!
