] I hope someone else managed to catch this fascinating film

I saw some of it. I was rather disappointed because of the extremely sloppy way in which the statistics were handled. The enormous numbers of prostitutes in London were quoted as fact, on unsatisfactory evidence, in my view, and then this picture by implication extrpolated to the rest of the country. But I thought some of the images, the shots of the still-existing buildings and so on, were interesting.
