Let's just make this clear: you might think a movie like Robot Ninja would be one of those transcendent B-movies that's good despite its non-existent budget, or that, failing that, it would be so bad and goofy that it would end up being hysterically funny and therefore a good time to be had by all.
But if you thought that, you'd be wrong. Dead wrong. Because watching the entirety of Robot Ninja will annihilate your very soul. I mean, I like camp as much as the next guy, but what I DON'T like is an hour and a half of pure torture, and there's simply no other way to describe this tenth circle of Hell. The only, only way I would ever recommend it is if you need to build up your tolerance for the worst movies of all time, so that you might be able to watch, say, Voodoo Academy without dying of lack-of-ambition poisoning, or Teenage Barbarians without succumbing to a fatal case of cultural shame. Other than that, stay far, far away.
In conclusion, Robot Ninja is the devil.
