Commenting on her work in Greenberg and other films, New York Times critic A. O. Scott described her as "ambassador of a cinematic style that often seems opposed to the very idea of style" and said that "Ms. Gerwig, most likely without intending to be anything of the kind, may well be the definitive screen actress of her generation . . . She seems to be embarked on a project, however piecemeal and modestly scaled, of redefining just what it is we talk about when we talk about acting." She made her first TV appearance on Jimmy Kimmel Live! in 2010.
