'The Office' is unmitigated pap. It may be a parody but that does NOT make it a sitcom. It may be a 'sit' but it most definitely lacks the necessary 'com'.
It is not that 'some people can't see the humour'. Its 'humour' is, as Arnold Rimmer would have said, invisible to 'anyone WITH eyes'.
What Arnold never mentioned is that some people deliberately put on blindfolds...
It is far and away the greatest sitcom con ever perpetrated, only recently being challenged for humourlessness by Little Britain and similar garbage where outlandishness is substituted for inspired witty writing.
It takes the Médaille d'Or as far as this thread is concerned. You can argue the toss about silver and bronze.
