I have this movie & I really enjoyed it. Though some of the special FX seem "over the top" (but then again, look at "The Matrix"), I rather enjoyed seeing some hot chicks kick butt.
Basic story is about 2 sisters who are paid to plant high tech viruses in big corporations. One sister dies & the younger sister must carry on with the job. The female cop who starts out chasing the sisters, eventually allies with the younger surviving sister to finish the job.
Hsu Qi (kidanapped girl from "The Transporter") plays the older sister, Zhao Wei (a very hot Chinese actress in Asia, right now) plays the younger sister, & Karen Mok (HK movie/singing vetran) plays the cop.
If you liked Charlie Angels, you'll probably like this movie.
