To enjoy this you have to take it for what it is, a movie made for fun with a low budget and no pretensions to be anything other then a campy B movie.
If you enjoyed the 70s-80s Japanese monster and robot movies with the rubber costumes you will enjoy this. I don't think the producers intended this movie to be taken seriously. It had robot geishas with swords from their bums, automatic weapons from their head gears, breast gatling guns and acid squirter's, giant robot castles, gun toting grannies etc.
Story wise its not bad either; mad scientist intending to blow up japan creates killer geishas with the top geishas turn into killer robot geishas. There isn't a lot of gore....unless you count the buildings that gushes blood when the robot smashes them. I think they must have had fun writing this movie.
Good movie. I liked it.
