As sordid and grim as a commercial product can hope to be yet wholly unenlightening about whatever it intends to be about, it can't be pegged as a mere feel-bad movie; rather, it's the ultimate feel-dirty movie. Not even technically virtuous enough to count as an exciting exercise in the thriller genre.
Gruelling movie with a heavy and difficult subject matter. The director keeps things tense and engaging throughout and manages both human misery that is hard to bear and thriller tropes that raises the pulse. The villain's motivation is a bit muddy considering the specific modus operandi that he follows. Shame. The acting is well handled but the character's are left a bit shallow. Still a good but disturbing film.
