I kept waiting for the various threads to weave into a whole and, eventually, towards the end it seemed to have done so, while perfectly maintaining the depressive and nihilistic mood of the piece.
I'm not sure this film had a point. It felt like a Coen brothers film in places, and I think that's what kept me watching, expecting some sort of whimsical or philosophical denouement. But no. Nothing but misery and death for no particular reason at all.
Perhaps this represents something real for some unfortunate people, and they have my sympathy, but the point o storytelling is to find meaning in live, not to bleach it of all hope.
If there are any redeeming qualities to this film I missed them. My advice, for what it's worth, is give it a miss.
