Having read the original manga, this does lose its impact upon re-viewing it, and while it does has its charm in its splatter aesthetics it is diminished by films which combined similar perversities with unexpected moments of depth. That said, rather than merely violent trash, it's blackly humorous Grand-Guignol that is entertaining and never becomes offensive.
The gory depiction of superhuman streagth struck me as more funny and ironic than most films that riff on the superhero genre, we need a film like this today. It's still very much a b movie with flaws like half assed martial arts choreography and hilarious dubbing. But the horror undertones are very unique if not fully realized, in any case I can say I've seen few films like it. Worth seeing.
