A change of pace from her earlier films, Mipo Oh's murky and perverse film was put up as a Japanese Oscar entry, so someone must have taken it seriously.
Ayano is working through his personal fortune in his twenties (open cut mining back story) when he lends his briquette to loud pinchuko player youth Suda, who invites him back to a home that's as grubby as Ayano's own. He shares it with his infirm sex addict dad, exhausted mother and earthy sister Ikewaki, who we know is going to be important because they play single piano notes under her shot.
A few attention getting moments. The embrace in the sea is one but the frequent shadowed make-out material is too indistinct to have voyeur interest.
The cast are strong and the Hokaido background is unfamiliar but the story and brown out imagery are both tacky.
