The only bad thing about this nanoöpus is that it sets up a little "Yes I can, No you can't" acting contest between Camilla Belle (Kira) and Dakota Fanning (Cassie), which the kid wins hands down. It also has some of the best Hong Kong scenery since Ghost in the Shell.
What can I say? I've always been a sucker for good Ψonics. I even like X-Men, although not as much as I like this one. I hope Fanning and "Miss Trouble" come back for the sequel. It's time to rescue Mom.
