"Johansson plays Lucy as a mouthy hanger-on who’s transformed into a ninja Carrie White in The Matrix. Chinese assassins move fast, but she moves faster. She’s not, I should point out, a vigilante avenger. She’s beyond human emotion. It’s true that someone accessing, say, 50 percent of her brain probably has more cerebral things to do with her time. But in a way, this is cerebral. She throws one glance at the advancing hordes and it’s a bloody Busby Berkeley ballet of flying bodies."
