Well, you (aside from CraigIsNotBond.com) appear to be one of the only Bond fans who disliked it. 
That's a sweeping generalization. I know many members of the general public that disliked Casino Royale.
Really? I don't. I'm not trying to be contrary, I'm just saying
everyone I've spoken to about CR (in person, not online), have really liked it. These are casual fans, mind you (hence they're the general public), but they've said it's one of the best Bonds of recent history.
As for tdalton, we've discussed CR to the point where we've just agreed to disagree.

(Though I will disagree one last time and say I thought Haggis' version of the ending was far superior to P&W's idea)
As for the news of Leiter's return, that's just another reason why I'm looking forward to Bond 22. I think all the news thus far has been very good, and I especially like that Wright's going to be back, because I thought he and Craig had great chemistry and that he was mucho underused in CR. This is definitely a good thing.
