I'm not usually a big fan of these TV four-part dramas that seem to be in vogue at present as they often veer into the absurd but decided to give this a go as it was based on true events and was most certainly not disappointed. Anna Maxwell Martin's performance as the key character was exceptional and even though she was the 'victim' she came across as an extremely difficult person to like and didn't do much to help herself. Overall, it was a bit clunky, had to cover a long time period and some of the other acting of the minor characters was a tad wooden but it did not spoil my enjoyment. It'll be interesting to watch the documentary with the real Delia Balmer to see if she comes across as prickly and abrasive as portrayed in the dramatisation - which she was even before her ordeal. I thought it was excellent TV and despite my negative opinion of Balmer, Sweeney is the unequivocal monster here.
