Talk about frenzy, this film is completely screwball crazy with guns and explosions on top! Quite literately a frenetic manga adaptation which is balls to the wall with massive fights, lopped off body parts and fountains of blood.
Its Japanese and you do expect this but even this is insane, the plot isn't too complex and basically revolves around a Yakuza assassin getting vengeance against the killing of his gang boss father. There is double cross in there too but this film is really all about the crazy ass effects and shock value gore. The cost doesn't look too high as much of the effects on show are your basic old techniques which range from looking effective to down right silly but this isn't really suppose to be more than a fun low budget B-movie.
Add in some outrageous CGI when 'Shozo' gets his arm replaced with a mini-gun and his knee turned into a rocket launcher (yep you read correctly) and you get some really quite daft looking results. Tonnes of carnage and a never ending stream of henchmen, both fun and stupid.
The only cast member I know of is good old Tak Sakaguchi and here he plays the main role, it suits him well and he looks good with his little porkpie type hat on. The whole film swings from slick and cool to down right ludicrous and will only appeal to people who like these type of Japanese ultra violent comicbook films. Personally I think the original manga comic probably works better, I haven't read or seen it but clearly its something that's hard to translate to film (bit Like 'Tank Girl').
