My wife is a science type person and she remarked that their is a lot of technical lingo being used here.
I reckon some person who enjoyed this series back in 1982 would had looked in horror when in 2005, Christopher Eccleston's 9th Doctor holds up a blue vial, calls it 'antiplastic' to fight off the Autons in the relaunched Doctor Who. The dumbing down of British television was complete.
There was so much talking in this episode, it came across as a polemic. What it was not was any sort of drama. I can see a younger me would had never watched this back in 1982. I think there was this thing called the Falklands War going on at the time which caught the nation's attention.
The older me was struggling even now, I think I just started to laugh when they started to talk about nuclear physics and thought this could be primetime entertainment.
Paul Brack comes across as a sixth form idealist who believes in the newer, cleaner and more safer nuclear power. He goes to talk about his future to a pioneer of the industry Max Challen. He turned his back on the nuclear industry and opposed it. Both nuclear power and weapons.
There were some good ideas that are relevant now, such as the future of cleaner nuclear power, renewable energy, hydroelectricity. It just does not make for a good drama.
