It must be difficult to be a screenwriter looking back on yesterday with today's eyes. I don't think they can win. On one hand all the awful, racist, sexist tv 'comedies' that were broadcast in the 60's and 70's are now mostly (rightly) unacceptable today yet here we are slagging CTM off for being unrealistic. There was horrible, nasty racism and women treated appallingly back then and it would make for really uncomfortable viewing. CTM has fallen into the 'cosy Sunday night light drama' category, especially once they ran out of storylines from Jennifer Worth's books.
But I do love the "suspension of disbelief" type posts on here though :-D
