You may not be the first to use this word, Morbius, although I do agree it should be much better known and more widely used.
Wikipedia has a page titled
'List of Sitcoms Known for Negative Reception'.
Among the sitcoms mentioned is one from the BBC called 'The Wright Way'
The Wright Way
A 2013 BBC TV sitcom by Ben Elton starring David Haig as the director of the health and safety department of the fictional Baselricky Council implied to be in Essex. The first episode received negative reviews from critics. The second episode was heavily criticised by Tom Phillips in the New Statesman, who found it to be even worse than the first. Adam Postans in the Daily Mirror called it 'the worst sitcom ever'.
Oliver Nagel of German blog britcoms.de included it in an article on "The Shitcoms of the year", commenting: "Worst. Sitcom. Ever.", "Gags that can hardly be described as such, dogmatism that speculates on approving laughter, gruesome characters – really everything is wrong here" and "With 'The Wright Way' Ben Elton has reached the very bottom."
