Indiewire:
Perhaps the greatest marvel in "Lucy" is Johansson herself, who's even better here than in "Under the Skin." There's a long single take of Johansson's face as Lucy talks to her mother on the phone, channeling the last vestiges of her former humanity before her ever-expanding mind wipes them away, that's as good as anything she's ever done, and all the more striking in contrast to the movie's rapid-fire montage. Besson's not shy about exploiting Johansson's primal appeal — Lucy spends an awful lot of the movie in a black bra and a white T-shirt, the better to show off the parts of the human animal that apparently need no further evolution — but he also gives her room, even within "Lucy's" minimalist running time, for well-crafted character beats, like the way the pre-evolved Lucy shuffles along in her too-tight skirt and the way her later incarnation confidently strides along on Louboutin stilettos. It's odd to say about someone who's been acting as long as Johansson, but it feels in some ways as if she's just coming into her true powers as an actress: She's evolving as well, and she's not done yet.
