This is not the thread to judge others' opinions, just to express your own and comment in a civil way.
My own: Sean Connery is the second-worst Bond, and a strong case could be made for the very worst. His smug, uber-cool attitude was completely out of place for the character Ian Fleming created. There were times when he allowed the real Bond to show through - getting physically ill after a tarantula had crawled up his body, for instance - but those instances were increasingly rare with each appearance.
Yet his portrayal proved to be the model for every actor that came after until Daniel Craig, who finally got it right. Timothy Dalton gave it a good try, but was unfortunately saddled with a script intended for Moore in his first outing and he never got past the second (where he did much better thanks to a script that rose to his skills, rather than limited by Moore's).
