How anyone can dis Carry On Emmanuelle is beyond me really, watch this and see why the british film industry went down the toilet imo.
But seriously....
It depends really on your sense of humor. Recently i rewatched CODick, and was surprised how flipping prurient it was, not that this is a recommendation cough cough. England i have to say is the nadir (due to lack of regulars really)
But then as a Kenneth Williams nut, i am very biased towards the ones where he shines out (Screaming, Follow that Camel, Matron etc)
