...is not so amazing.
Found this off a random thread on Myth-weavers: http://ireport.cnn.com/docs/DOC-623458?hpt=hp_bn1
And here's my commentary.
Lots of Kiai, no form whatsoever. She was also wearing the sword wrong. She wasn't cutting anything. Lots of noise, but she was handling the sword like it was a nunchaku.
She can definitely go pretty far, but she needs a better teacher. Also, letting someone train by him/herself means he/she will be making tons of mistakes and developing bad habits. While her agility is impressive, her martial skill consists of lots of impressing and little focus.
I'm not saying her moves aren't impressive for a girl her age. They are. But the day a little girl like that kicks MY butt is the day I sign up for vasectomy.
