A couple of favorites: Jodi Dean and Bill Krohn.
Krohn is known to cinephiles for his books Hitchock at Work and The Complete Films of Luis Bunuel as well as his articles in Cahiers du Cinema, especially his piece "Hollywood and the Holocaust." Always an insightful culture critic with a nice prose style.
Jodi Dean came up with the theory of "communicative capitalism" that she discusses in various articles, and I liked her recent book Democracy and Other Neo-Liberal Fantasies

Having a section dedicated to Tolstoy in a history of anarchism isn't a specific criticism?
It's nearly ten years since I read it so other specifics are failing me a bit, and I don't have it to hand, but given tobias' summary it's even worse than I remember - anyone who doesn't like authority is an 'anarchist', anarchism's relationship to actual historical movements and class struggle largely brushed over. It's a bit like if you had an uncle who vaguely liked anarchism then got a book deal.
