There are some good Dalek stories after this one. Some very good ones, in fact. But I really don’t think “Genesis of the Daleks” has been surpassed by any of the Dalek adventures that have come since its 1975 broadcast. And it all comes down to the last seven minutes or so.
Honestly, this last part is a little flabby. The Doctor’s debate about blowing up the incubation chamber and killing all the infant mutants inside is rightly remembered as amazing. It’s good that it takes a minute to address the issue: the Doctor is about to commit genocide. The only Daleks that will survive are the ones in the death squad that’s been recalled. It’s left to these eight or nine to spawn all the Daleks of the future.
Interestingly, this story has sparked all sorts of speculation about what, exactly, the Doctor actually accomplished here. Did he change the future in some way? Did he cause a long enough delay to force the Daleks that we see later in the program to be less scheming and less successful?
On a related note, I really like the retcon that Russell T. Davies introduced, that once the Daleks somehow figure out that the Time Lords screwed with their development, this story becomes the first strike in the Time War of his era. I remain disappointed that something that could have been mythic and almost impossible to imagine, let alone visualize, a cosmos-spanning event that rewrites all of galactic history with every campaign, finally made it to the screen as a bunch of silly men and silly robot-things shooting each other with zap guns, but I think that Davies had the right idea. If the Daleks absolutely had to be the Time Lords’ opponent in the War, then making “Genesis” a preemptive strike is a great idea.
Minus that scene, the first two-thirds of this episode is padding and flab, and then the Daleks make their move and it’s incredible. I love how they don’t talk for a few moments. They just murder Nyder. Then they kill all the extras, after letting Davros know that they do not understand the word “pity.” I love this all mainly because they’ve been obedient little killers, agreeably doing whatever Davros tells them, until they all get together and exterminate everybody. It’s a fabulous climax.
But with it goes the greatness of the old Daleks. The scheming and the quiet manipulation of “Master Plan,” “Power,” “Evil,” even “Planet” really gets replaced from this story on, at least until the Time War. The Daleks that we see in the rest of the classic series just aren’t as effective, in a narrative sense, despite a couple more good stories. And Davros, sadly, doesn’t stay dead, again despite a couple more good appearances when Julian Bleach is in the chair. So I guess the Doctor did accomplish something after all. He made the villains so much less entertaining!
