I wouldn't mind the explicit sex humor if this totally absurd movie (which could only come out of Japan) was actually funny. I mean, it IS kind of funny in a sense that such a bizarre, crazy and stupid story even got made into a film. At times it reminds of a perhaps a bit overly creative porno with the sex scenes cut out. Maybe stoners would find it hilarious, but watching it sober it didn't make me laugh once. It's just bad.
