This is a rarity in anime, for me. An independent film which comes off far worse than Ark.
This anime really doesn't have anything other than cunnilingus, phallic imagery, lots of dicks, and only once - and I repeat, ONLY ONCE - does it show anything remotely resembling "Fetish" (a woman who is tied up, one of the gagging role plays in a Master-Slave fetish setting). There is no point being made other than being "visually stimulating" (which it isn't to be frank), or "thought provoking perspectives being provided" (which it doesn't), or "a strong statement about our society which is objectifying women" (which is hardly ever presented or elaborated other than just stating it like an object - intended irony? I don't think so).
If people are into such snowflake attempts at being "adult" or "involving" its pretty much going to be a disappointment. Skip this unless your willing to give your curiosity a moment to digest this LSD type trip. It isn't a "fetish doll" movie, which makes it grossly disappointing to say the least. Either way, a waste of time.
