Does it really matter what they look like? I love Corin for what she is. Happy, balanced, human being. She has a thoughtful respect for the other housemates. She actually listens to what they say and has sound advice for those who look for it.
She comes across as someone whp is happy with their lot in life and is enjoying BB. I thought her voice would irriate the live out of me but it has grown on me.
I don't find Corin dull in the slightest. She is good fun and not out to find the worst in people.
