The 2 Geordie lasses (Georgia and Abbie) are quite funny, but like a pp, I can't believe they are as thick as they present. No-one can be that thick!
Sophie and Pete are my fave of all. 
The 2 (older) Scottish sisters are dreadful. (They're quite new.) As a pp said, they are so contrived, and trying to be funny/trying to be 'characters' and it's not working.
Also dislike the elderly mum and her middle aged daughter with the dreadful, ugly glasses.
The same sex couple (men) one 60-ish, one about 30, seem quite endearing. Wasn't sure at first, but they are growing on me.
The same sex couple (women) who always sit together on a couch (just past middle age,) I'm not too keen on.
I miss Mica and Marcus too. Also Steph and Dom.
I don't miss the hairdresser and his partner(s.)
Who is Simon? (A few people have mentioned a Simon...)
