We absolutely love it. English, so the accent isn't an issue for us, although we have friends from Derry and it passes to our ears (I suspect they are posh Derry though). But it's so well written. The chip shop episode is my favourite so far I think.
Saturday Night took very little rehearsal though, I bet. That's exactly what happened every time it was played - whole rooms full of people doing that ludicrous dance in unison. Most of us didn't have any formal dance training.
