Oh man! They didn't even use a legitimate ninjutsu practitioner. The ninjato? Really? And since half their weaponry was distraction weaponry, of course the computer determines the Spartan the winner.
What about next week's episode? Pirates vs Knights. What could the pirate possible do? It should have been pirate vs ninja!
SPOILER ALERT - FINAL SCENE SPOILER
Do ninja normally grunt aloud like that while sneaking up on an opponent with a sword? I guess it wouldn't have made for a very good show if the Spartan were finished in 7 seconds. The Spartan also made a very nice recovery from the black egg to eyes and was able to track the Ninja down through the woods where the Ninja rolled out into a wide open area to shoot the poison darts where with the immediately restored vision the Spartan was able to drive his blade into the Ninja.
Also, earlier in the show they showed the ineffectiveness of the Kusarigama blade against the bronze armor. Would not a Ninja attack the shoulder, neck, or underarm of the Spartan if he were that close?
I was disappointed in this episode, but it was still probably the best thing on TV. LOL!
