As you can see by the trailer here, it's basically a movie that elevates autism  to the "Indigo Children" level,  giving Zen, the main character, supernatural martial arts abilities as some sort of compensation for emotional/social detachment.

7 out of 10. 

 After an initial burst of action, it slows down for about 30 minutes to build the story.  It was decently put together and well shot, but not really what I look for in my brain development disorder based kung-fu flicks.  Regardless, she becomes superhuman just in time for her mother's cancer bills to become an issue.   She has a lacky (Moom?), who, as a bumbling fool/comic relief, trys to collect the money from people the mother used to extort from, like 10 years prior.  They still remember the debt, but everyone tells him to go fuck himself.

Zen comes to the realization that her mother is owed this money and goes back at night to collect it.   Same reaction, but this time fists are flying.  It makes for some interesting fight scenes, one at an candy warehouse, one at an ice warehouse, one at a meat prep factory.  These fight scenes beg the question, what kind of loyalty do these factory bosses demand out of their employees?  Are they all family members?   I can't imagine any company in the US where I might be asked to attack a little girl because she's asking for money.  Even less, where I would attack without question when asked.  Maybe the unions demand that kind of obedience.  I dunno.

 It was a fun watch, and I'd recommend it for fighting flick fans.  A highlight for me being a mirror match that she has to fight someone with some other non-specific brain issue (looked similar to Tourette's to me).  It's a classic, and her finishing move is quite an amazing feat of human flexibility.
