Some critics have argued that the character is underdeveloped, but anyone who says that isn't watching closely enough. Maya may not be given a traditional back story (all we know is she was recruited into the agency after high school), or any outside life to speak of (even Renner's unhinged Hurt Locker vet is shown going home to a wife and kid), or the desire to distract herself with romance ("I'm not the girl who fucks ... it's unbecoming" she explains at one point, dismissing a colleague's inquiry into her social life). But there's plenty of interior life there, and it comes through in quick, vulnerable flashes — leading up to the payoff of the film's devastating final shot.
