The hairdresser scenes in Coronation Street always make me laugh. Not one of the supposed hairdressers look as if they have any clue whatsoever about hairdressing.
Although I have watched and enjoyed Coronation Street for many years, I am reluctantly finding myself in agreement with some recent posters who said it is becoming more and more ridiculous. The characters of Brian and Kathy I find extremely annoying and unconvincing - and some of the plots relating to them quite absurd. Ditto Rosie and her sister doing a window cleaning round and Norris and Mary planning a fake wedding in order to enter a competition. I am starting to lose patience.
As someone else said up-thread, why can't soaps be more reflective of real life? The boring bits can still be cut out, but have people watch telly, go on holiday, get jobs outside the neighbourhood and commute, have (believable) disputes with neighbours, argue about politics and religion, etc. etc. Or perhaps that would be too controversial and it would be hard to achieve balance?
