I understand all that is said here, the era and the fact that this was his first film but I found the film to be rather heavy-handed and too styistic, too New Wave, to accurately represent the book (in my opinion). The second film, if 2004, erred a bit more towards romance so so missed accurately representing the humanity of the book, I think it was more accurate than the first by focusing on human beings, which, to me, the first film did not.
