Dark and edgy seems to ne the Hollywood standard at the moment, some films it works with and some it doesnt. Look at Batman for example, from the Tim Burton version onward the films were a mix of dark and camp but the new reimaging with Christian Bale has meant that you finally have a Batman character that is true to the original concept. Bond should work in the same way as the character in the novels is far darker than has been protrayed (sometimes possibly even borderline sociopathic) but it may take longer to be accepted as people are too used to the old Hollywood version.
