The ratio of mad to sane women was so extraordinary that I actually enjoyed it. 'Let's interview the girlfriend of our chief suspect.' Yeah, wonder whether she's mad or not? Oh, what a surprise.
I could take offence at this, and I don't blame anyone who did, but I thought it was quite funny and ridiculous, and so far from any connection to reality I didn't mind. If it didn't have Elba and lovely Ruth Wilson (guess what her character is like?) in I would probably drop it, but as it is I will probably watch more episodes.
