Robot

Suffering from fatal injures sustained during his last adventure, the Doctor has regenerated yet again.

Comments with major spoilers: 

Robot was the first Doctor Who story that I saw way, way back in the day when I was a teenager. It aired on the local PBS station and was preceded by a special announcement. A short commercial of sorts explaining what the heck the show was, because apparently American audiences would be lost, dazed and confused at a British show that was not a period piece drama or a low brow sitcom. This was different. This was science fiction. It was great and I was very quickly hooked and still am to this day. 

Transitions:

Robot is Tom Bakers first story and it quickly becomes clear that he is going to be quite different from Jon Pertwee's Third Doctor. Gone is the stylish dandy action hero spy who claims to only begrudgingly assist UNIT, but seems in fact to rather enjoy it (when they being idiots that is).  In his place is a new scruffy bohemian Doctor who has to be cajoled into remaining on Earth. 

Interestingly, compared to some of the later regeneration stories, especially in the new show, the "post regeneration crisis" is taken care of relatively fast. It's "oh no he did it again, we have a new actor playing the Doctor, er the Doctor has a new body!" followed by the now standard let's make fun of my new face jokes. Then he's on his game again ready to solve mysteries and fight monsters before the first episode is over. 

Nerd nazis:

The story introduces a top secret scientist group, the Think Tank (the National Institute for Advanced Scientific Research). They last for about a minute before being exposed as fascists who aspire to have scientists rule the world with an iron fist. The Think Tankers end up being not so much a metaphor for nazis as much as they are just out and out nazis. Nerd nazis at that. All the dweebs and geeks who were bullied in school have become scientists intent on global domination because only they have the smarts to know how to do the job. 

Except that they don't. For all their intellect, they are a bunch of idiots with delusions of grander. Also, just in case science nazis threatening the world with nuclear holocaust didn't make it obvious that they were bad guys, there is a scene where they disapprove of Sarah Jane Smith because she was wearing trousers instead of a skirt. So remember, despite her frequent decent into very bad 70's fashion, dissing on her clothes is a sign of evil nazism. 

Reading stereotypes:

Professor Kettlewell, the creator, the father, of the titular robot visually "reads" as an Einstein stand in. So in essence he is Jewish in feel if not fact. This adds an interesting wrinkle to the big reveal about his involvement with Think Tank, which to be frank is about the only interesting thing about them. 

Kettlewell is not the only coded character in the story. Intentional or not, Hilda Winters, the female director of the Think Tank reads as a lesbian. It's not overtly implied, but given her 'severe' appearance and her constant belittling of the men under her control, she ends up sort of reminiscent of a bad stereotype of a villainous man hating lesbian. Well, at least as much that would be allowed in what is still technically a 1970's kids show. Even so, it wouldn't be too hard at all to picture the character as a women's prison warden in a low budget exploitation flick. This interpretation could be potentially offensive, but I'm jaded enough that I find it more silly than anything else. 

Silly is a good word for the reasons that another character could be perceived as gay, that is experimental robot K1, himself. 

As designed, he has heavy clamps for hands at the end of long thin arms. This has the effect of making him seem limp wristed. Given the existential angst he goes through towards the end of the story where he goes around wailing and flailing his arms about, he comes off as a big drama queen. 

While it sounds like I don't like the design of the robot, I actually do. It hits that "sweet spot" of low budget science fiction show clunky but cool. Not so cool is the final King Kong homage sequence, where he becomes gigantic, and clumps around a village killing soldiers and carrying Sarah Jane Smith as the Beauty stand in. Unfortunately given the finances and skill level at the time, nearly all the special effects end up being rather embarrassing looking. 

Bad giant robot visuals aside, over all the story is better then not. It's a bit of a confusion of styles, which given the show was in a period of transition, both on screen and off, it's not surprising it ends up being a frothy mix of a Third Doctor UNIT / abused science story combined with a Fourth Doctor monster movie homage. Still again, it's not a bad story. More of a average tale. 

Death rate: 

Several, though not especially high. There are multiple onscreen deaths, mainly UNIT soldiers, but for the most part people aren't dying wholesale. 

Random bits:

• We get to meet Dr. Harry Sullivan who becomes a companion by the end of the story. 
• Hilda Winters is aptly named, given that Hilda means "Battle woman" and her world blackmail threats would have resulted in a nuclear winter. 
• I like how the show uses the point of view of the robot at the beginning of the story. It makes it clear the "culprit" is mechanical, yet it so strange looking that it still manages to add to the mystery.
