I don't think it was particularly political.
We all know Danny Boyle's leanings, but the stuff he 'slipped in' (like the CND logo) seemed to be completely relevant to the era that the music was portraying. In any case, I'd argue that you can't (or indeed shouldn't) airbrush out politically sensitive or embarrassing events as if they'd never happened. The CND marches, Greenham Common etc were valid, if maybe misguided, reactions to the very
real threat of a nuclear holocaust and I can't see any problem in alluding to them.
I thought the whole tone was kept just right, and never strayed into "
political theatre" at any time. And there was definitely no trace of any jingoistic/triumphalist slant coming through in the events depicting the history and heritage of Great Britain. If anything, most of the history lesson was given with a wry sense of humour, slightly self-deprecating and definitely tongue-in-cheek.
There was, for me anyway, a slightly uncomfortable irony with the passage dedicated to the NHS - I couldn't help thinking that it could be viewed as slightly obscene when, as a nation, we can find billions of pounds to fund an Olympic Games when said NHS is on its knees. Mind you, having said that, even if they poured that amount of money into public healthcare it would make little more than a dent.
But on seeing the collosal expenditure, it must appear quite repugnant to anyone on a three-year waiting list for a life-saving operation, or being told that they can't get funding for life-changing medication because they live in the 'wrong' postcode.
