Being one of the rare breed who still find foul language unacceptable, I expected to switch off after ten minutes due to the "it's after nine o'clock so we'll swear because we CAN, whether it's needed or not" brigade, but was pleasantly surprised to find there was only one swear-word, which proves a point, does it not? It didn't need it. Well done to the producers for that and I hope the remaining episodes will follow suit so we can ALL enjoy it. I thought Katherine Kelly and Daniel Mays were brilliant.
