"[Scarlett] Johansson plays Lucy as a mouthy hanger-on who’s transformed into a ninja Carrie White in The Matrix."
David Edelstein, Vulture
"For himself, Besson manages two intriguing bits: When Lucy kisses an Arab cop (Amr Waked) and tells him 'You’re a reminder' and a DePalma-style scene where she likens fast-motion film to human experience: 'Time is the only measure of existence.' Flashy and pithy. Take that, Richard Linklater!"
