I too read AA Gill's review and I quickly got the impression that he only watched the trailer, waited for other people's reviews and then quickly cobbled together a few words that were designed to be contradictory.
To imply any political bias is self-important posturing and absolutely laughable. It is a true account of events, told more or less as they happened. As I mentioned before, the accents are positioned 100 miles too far north and I'm not convinced of the need to bring it forward to the Brit-Pop era. Having said that, the tracks used do actually work quite well.
One thing I did pick up on was the occasional use of the word "like", which I don't think became a teenage girls' speech impediment until about five years ago.
"Like" has been used like that for a lot longer than that.
AA Gill also said that the programme was like something that would be shown at school with pauses after scenes so the class could have a discussion and that is the feeling I had already got from the trailers, that it would be dull and worthy.
