Masumara leers into the darkness of lust and wild abandon coupling it with need, desire and malformed childhoods. The setting is a large factory composed of "sculptures". The story is about the psychological need to feel something, anything to exist.
The film is uniquely Japanese in its willingness to portray loneliness, need and lust. It moves forward at a Masumara slow grind to the eventual conclusion.
Another milestone for Japanese sensibility, exploring the potholes of the human psyche. It is slow ponderous and some people will be bored before before they become disturbed. Certainly the ending is not predictable from the beginning unless you have intimate knowledge of Masumara. The exploration of issues relating to the sexual needs of people who have disabilities, the power of eroticism, the potential stifling nature of mother/son relationships and the role of art.
There are holes in the film, unexplained events but this is primarily an allegory rather than reality. Red Knight concerns the real, this moves somewhere else.
