i never saw the other two ninja movie and for all i know there be know and but for some reason i watch this one . this one start out rather fast a this one ninja go on a super killing spree . he be almost unstoppable a it take quite a number of bullet to take him down . he be not out for the count though a he end up possess a woman and he then continue his kill way by use her a his tool . another ninja enter the fray and apparently the only way you kill a ninja be with another ninja so he volunteer . this lead up to a big battle at the end a the dead ninja go back into his body and they have it out in an all out war . sound well than it actually turn out be and but at least it be not boring .
