Chop off a few heads, splatter some blood, and I'm happy. It would have been grand to see this on Sunday for International Day of the Ninja... in ninja garb. Dayum, I could have cashed out with that.
In retrospect, it really bothered me that when Jang did a chiburi (the final sword flick to shake the blood of the blade) the blade was still bloody. Granted, chiburi is tough. I've tried it when I used to practice iaido. We experimented just with water, and that's pretty hard. Blood would be even harder as it's stickier. But Jang was supposed to be the best swordsman ever, so you'd think he'd be able to do it. I know there was at least one scene, maybe more, where Jang does a chiburi and then the blade is shown immediately after still dripping with blood. It was a classic example of filmmakers observing some martial behavior and not understanding it fully.
