I'm going to miss Brosnan. I think two of his Bond movies, Goldeneye and Die Another Day, were very good. Tommorrow Never Dies had problems, but it was O.K. It at least had Michelle Yeoh. The World is Not Enough might be the worst film of the franchise(it's between that and View to a Kill) and I almost didn't go see Die Another Day because of it.
I think Clive Owen would make a great Bond. Bana wouldn't be too bad either. I haven't seen Gruffand or Butler in anything where they have required a personality. The one rumor that I am dreading is they were talking about Orlando Bloom. If they choose him, I will refuse to see the movie.
