This emotional core elevates Shadow Ninja above a simple revenge plot. Kaze isn't trying to kill the bad guy because he is evil; he is trying to get home for dinner. That vulnerability makes the violence matter. No great shadow exists without a light to cast it. The villain, "The Lantern" (Maya Sakamoto), is a former kunoichi (female ninja) who betrayed the clan. She wears a suit of fiber-optic-lit armor—literally becoming a blinding light in the dark.

Shadow Ninja respects the legacy of the genre (you will spot homages to Enter the Ninja , Ninja Scroll , and even Teenage Mutant Ninja Turtles ), but it drags the ninja, kicking and screaming, into the 21st century.

But then you watch Shadow Ninja .
