I can't imagine thinking through Hitchcock, Hawks, Queer Cinema or Horror films without Robin Wood. He was the humblest (his critiques were always in a state of potential revision) and most plain-spoken of all the great theoretically driven critics (never letting theory or dogma dictate his own reactions). Although he did tend to overuse the "to not love movie x, is to not love cinema" (e.g., Marnie), that was part of his charm. Truly one of the good guys.

Summary of his career.
