This is an outstanding film, but it isn't for everyone.
It isn't a slasher-screamer-jump out of your seat flick. No no.
This film gained my shocked interest immediately, and to be frank it was held throughout the rest of the ride.
This is definitely not a film for anyone who has recently suffered a loss, in fact it should be viewed by the loss-experienced only when they have completely recovered and can look at anything. Preferably YEARS after they've fully recovered, because it will take you right back to the grimness of deep loss and the eternal question, why ?
For those who work in the field, or have seen others go through loss and grief, or have experienced counter-cultures on a personal basis, this film is an incredible insight into the workings of twisted minds, no matter be they rich, poor, in-between or socially minded misguideds who treat their clients like fodder.
Superbly acted, very well crafted and a sensible and life-like script and dialogue are to be rewarded with praise indeed.
Just be sure to be aware of your mental strength before you embark on a true roller-coaster ride that is definitely not by proxy....
