How bad is it? It's more bizarre than bad.
Should you see it? Yes.
This is yet another film that I've added and deleted a few times on my bad films list, as it's a pretty good ninja film, better than the previous two Sho Kosugi ninja films done by Golan/Globus. A ninja on a golf course kills a whole bunch of people, takes an unbelievable number of bullets and transfers his soul to a young woman who works for the phone company and teaches aerobics. The film has endless musical interludes, with a lot of creepy aerobics studio voyeurism, but also a good number of adequately done martial arts sequences. Best scene is stopping a gun by blowing a dart down its barrel. Bottom line: it's not boring.
