 James's work has remained steadily popular with the limited audience of educated readers to whom he spoke during his lifetime, and has remained firmly in the canon, but, after his death, some American critics, such as Van Wyck Brooks, expressed hostility towards James for his long expatriation and eventual naturalisation as a British subject.Other critics such as E. M. Forster complained about what they saw as James's squeamishness in the treatment of sex and other possibly controversial material, or dismissed his late style as difficult and obscure, relying heavily on extremely long sentences and excessively latinate language.Similarly Oscar Wilde criticised him for writing "fiction as if it were a painful duty".
