It is Los Angeles in the year 2032; Elle, a young woman, wakes up with no recollection of her past. An early confrontation shows that she is highly proficient in martial arts and other combat skills. She sets about finding out who she is; once she has learnt enough she sets about getting revenge on those who abused her and those like her.
I know a lot of people were disappointed by this but I really liked it. I thought it nicely captured the feel of the Blade Runner films. At first I was unsure about the 3D animation but once the action started I thought it was great. Some may say the characters could be more realistic; I'm not so sure... the closer animated characters come to looking human the more one wonders why it isn't live action. Elle is a fine central character, even if her big twist which is revealed very early on, will be obvious to most viewers. The story moves at a decent pace. Overall I'd certainly recommend this to fans of 'Blade Runner' or animated sci-fi action in general... at least give it a go; if you don't like it you can always drop it.
