As other reviewers have noted, this study is a terrific analysis of how early film could be an open, more interactive medium. But it is valuable for more than its contribution to the history of film. Hansen combines her study of the history of film with two other areas--1) empirical study of the reception of early film (the opportunities for collective sense-making by populations such as women and new immigrant groups), and 2) theoretical study of the way film changes our ideas about the public sphere.
It is the methodological richness of this book that makes it such a powerful work. Readers are offered astute, inventive close readings of films, informed discussions about historical reception, and cutting-edge ideas about what a mass-culture medium like film might mean for our ideas of public reason.
