Funniest movie ever made!!!
I remember buying this film, unknowing of what it was; the first part of the movie was strange and not very good - but when the socalled "final battle" emerges between our hero (yellow ninja) and the villian (red ninja), the fun just keeps coming... If you ever find this movie somewhere (for a reasonable prize), then buy it by all means; the last 30min is well worth it.
You'll never see a stranger and more unserious ninjafilm (except for maybe Kung Pow) - but that movie never tried to be serious; this one does and fails miserably!
