... I have to be honest and say that before I sat down to watch, I hadn't given much thought to the subject, myself. Maybe it's the suburban boy in me. Often you don't notice the true depths of depravity to be found in most cities unless you actively go looking for it.
This happens to be about the underbelly of London; and what practises are reputed to - and may or may not - go on there. In this particular treatment, such activities are allowed to continue because the people caught up in them aren't citizens. 'Developed' society prefers to deny them a workable route of admittance for many of their circumstances;, so the best attitude seems to be to ignore how they have to live until such time as they go away. Of course, the logical outcome of such a way of thinking is a marked increase in illegal/immoral activity; but somehow the people who wish to turn a blind eye can't understand that eventually the overall effects will begin to seep onto THEIR doorstep... You do indeed tend to reap what you sow.
For those lucky enough to be ignorant of the sorts of happenings that take place on the streets, one can only say that this film is an eye-opener. Too often we walk around blind to the foreign nationals who do a lot of our menial jobs for us. It's not expected that we take notice of our cab drivers, chamber-maids, and yes; even our sex-slaves. Pity we don't pay more attention, because that often isn't ALL they do; and the burden of truth should heap shame on civilisation as a whole. These issues are handled brilliantly in "Dirty Pretty Things" by all of the creative team involved. See it to humble yourselves with this sobering reminder: The face you slap on your way up may belong to the same owner of the feet you're kissing at your lowest ebb.
