I find his work, sometimes, a bit too literal. I never really thought the Brown sisters series was all that interesting. There's no context, and very little emotional or psychological interplay between them. For years, I never quite got Nixon's work. Having said that, in 1999 or thereabouts he published, with Dr. Robert Coles, a book called "School" which is really very good. Much more context, and emotion, and Coles' essays, though it's been awhile since I read them, are full of insight. You might look for this book instead next time you have forty bucks to spend!!
