There is lots of great stuff associated with this movie, unfortunately it is the prose of the various newspaper critics who are doing their best to make sure everyone involved is never allowed near a movie set again.
Even if the critics are trying to ensure the guilty parties are never allowed near a film set: that's hardly an unreasonable ambition. Who thought let's get a quite pleasant saturday tea-time celeb, a pop-singer and a really-annoying d-list cockney and put them together. Can't think why it's been slaughtered. Oh right well the sexism and homophobia apart etc...
Well no wonder the critics slammed it--why at this point in time would anyone want to make a movie of a decades-old Ray Cooney sex farce? I saw my first one in the mid-1970s and it seemed hopelessly dated even THEN, with all that smirking "Oh dear I can see your naughty bits!" kind of schoolboy humor. Michael Frayn's "Noises Off" pretty much buried the Cooney school of farce forever, by parodying it so ingeniously.
