I think some people should refrain from talking to the press. :) It's probably true that MM appeals to a certain market, both at home and abroad, that like their dramas to be 'period', chocolate-box quaint and nothing like real life. Which is OK because we have other audiences for dramas which are gritty, edgy and also nothing like real life. There are no ethnic minorities in MM for the same reason as there's no-one over 30 in Hollyoaks... image.
All that's wrong is for the producer to let the cat out of the bag.
