I can see how it might have been a reasonably good read, but as a TV drama it just became more and more ludicrous. The plot was so contrived, it made no sense whatsoever, it continually contradicted itself. I know liberties are taken for dramatic effect, but this took the biscuit. Some of the lauded British modern dramas that have been screened recently are an insult to the discerning viewers intelligence, but this one takes the prize.
