this film make several nod to various science fiction film . the prologue remind me of the one for the original theatrical version of thx 1138 ( the trailer for buck rogers and here it be clip from some early japanese sf tv show ) . then the opening shot of the city in 2345 have the dragon blip fly overhead with a billboard and remind one immediately of bladerunner . the bladerunner aspect come evenmore pronounced when we meet the hero and who be call a replicant ( he be blond haired and be call ryo and a homage to roy batty and rutger hauer character in bladerunner . ) . a battle scene soon ensue which remind one immediately of the matrix . the government force the population to take drug be like thx 1138 and the chief enforcer and while look like a cross between elvis and dan ackroyd and turn out to be a robot and very much like the terminator . the end battle remind one of terminator 2 and the end result be hilarious . probably not one of the best sf film out there and but be enjoyable and certainly a lot more enjoyable than tripe like battlefield earth .
