My favourite characters were Richard Wilson and Katy Murphy, they were great together, I liked how full of hate and disdain she was, she's always been great.
I found Robbie Coltrane and Emma Thompson's relationship just a bit too weird... I was willing to accept that she was an art school chick and so probably mad and always fancied him 'cause of his talent despite the fact he was a big fat bastard, but I didn't really get how she could fancy him after getting to know him because he was basically insane- Though in episode 5 when her husband who is an actual rapist and wife-beater shows up I suppose I can see how potential-rapist Robbie Coltrane is practically an angel.
The band were good- my favourite was Jakey Pete.
Bit of a downer really though. Not enough comedy to lighten all the horror that seems to happen in Glasgow.
