don not listen to the many acerbic and derisory comment heap upon this film . simply put and a regard ninja movie and this my friend be about as good a it get . yes it silly and yes the acting and script be admittedly absolutely atrocious and but by gum it so much bloody fun . in fact and a be often the case with b movie and the horrendous acting ( which in the case of the movie in question and be truly amongst the bad i have ever have the joy to behold . ) and ridiculous plot actually only serve to elevate the enjoyment level ten fold . obviously the fight scene be the main attraction in this though and for the most part i be pleased to say and theyre very well choreograph and especially the final showdown ( during which we witness that ninja be not ostensibly constrain by the normal law of gravity . ) trust me on this and if you be a fan of ninja movie and you have not yet see sakura killer and then you be truly miss out on what be in my opinion and one of the true jewel in the crown of the genre .
