Do not believe the critics. This movie sucks!
It does well in Asia, because Asians don't know good film. Most Asian film is horrible. I just saw the film on 3-3-19. It was not the worst film but I certainly would not call it good. It was trivial "girl power."
The movie has a female cyborg hero that is likable, but not so likable that a movie should have been made about her. A trivial movie based on a stupid book. Her back story is convoluted and creates more questions than it answers. The performances were mediocre. The special effects were pretty good.
The film lists Michelle Rodriguez, but I don't remember seeing her. She must have been one of the forgettable killer cyborgs.
Save your money and catch this on DVD.
There was a lot of giggling in the film. When the movie let out, I could see it was a group of young Asian females and a few males. That's it folks...a movies for young girls.
