I came to this discussion after watching a series of classics (Third Doctor, Season 10, Green Death), where there is a series that is too similar to a series with spiders in season 11. It feels like Chibnell took the idea from here. Or just coincided.

In classics, there was also a clear topic of ecology (even one of the important heroes was an environmental scientist), the main antagonist of the series was a gasoline manufacturing company (led by an evil supercomputer, but this is not so important), which dumped a lot of harmful wastes, for which, under the ground, huge mutated larvae began to appear (which is even more vile than giant spiders) that infected people, and they died. And then they crawled out from under the ground and could turn into huge dragonflies, which was very dangerous.

I recall that mutated spiders at Chibnell also appeared due to hazardous waste.

I think if the storyline with a supercomputer that brainwashed everyone to help the company flourish and the personal storyline of Dr. Joe Grant’s companion were removed from this series, then we would have gotten a series similar to the one written by Chibnell. It’s only more interesting, more fun (it was from this series that a meme with the “Granny of the Sacrifice” came from), and without morality “on the forehead” about ecology (because here this topic is shown clearly, it goes through the entire series, and morality is not read to the viewer somewhere at the end of a long monologue). Although, without a storyline with a supercomputer, I think the series would not be so exciting …

And now the question. Why is the series with a similar message and complication, shot in 1973, much more interesting, more fun and less frenzied than the series shot in 2018? And at the same time does the message about ecology quite reach the viewer?

I understand that in the 1973 series there were 6 episodes of 23 minutes each, and in 2018 only 43 minutes were given (= 2 episodes of the classics).
