this film is astounding. i saw it at a local festival a few years back and i loved the texture of it. It was ominous and thought provoking, mature and psychologically thought provoking. You don't normally see this kind of thing out of AFTRS so I must say well done to the director.
If you like this also check out Mairi Cameron's "Milk" also an excellent graduating film. They both make Cate Shortland short films, "Joy, "Pentuphouse" look like style over substance. I hope this man, Heng, goes on to make some more work. There is something going on here and it's worth checking out.
