It's not just her hair that's bad, I don't think I've ever seen a collection of women with such bad hair.
I thought Michael and his mother were both equally guilty of judging her purely by appearance, but Michael's even more guilty than his mother after this episode, imo.
The amount of surgery, time and effort she's put into looking as bad (imo) as she does is astonishing to me and I think Michael's mother is right to be concerned about her debt load.
Michael's appears to be smitten though and the harder his mum campaigns against her the more he seems to like her.
Mum might have to back off and let it run its course, unless the aim is to show that mum was right all along and Mike will come to his senses by series end.
