Just watched it and I enjoyed it. Agree that Michelle was brilliant, very very funny and well observed. Not dying about Erin (bit OTT) but I often find the characters that are supposed to be the "normal" ones in sitcoms are the most boring. It's nice having a comedy show set here, I don't want a gloomy gritty programme with the backdrop of the troubles. If you want that stick on Spotlight.
It might have been posh-Derry accents but if you want a program like this to have mass appeal I don't think you could stick with a thick Derry accent. So many jokes and parts of the dialogue would be lost on most people from outside NI/the border area because of the spreed and how broad it is. You should hear how my Co. L/Derry cousin sounded after her first term at uni in England, she had to slow it right down to give people a chance.
