I agree with ferlew, I don't mind watching something by myself and so long as there aren't any glaring errors, I'm not really fussed, but if I'm watching some programme with the OH, he picks up on anything that might be slightly wrong - especially if they happen to be old vehicles; e.g recently, some elderly lady getting on an old bus in a TV programme (maybe Heartbeat?) and being told that that bus wouldn't have been doing that route as they did not bring out that particular bus until 2 years later, you can tell by the split windscreen! I am so glad we have two TV's!
