C'mon, DAD's financial success was down to marketing and the brand, not word of mouth or critical acclaim, which both quickly soured.
Sure every new actor may find a comparison to Connery, but only Craig has maintained if not improved upon that comparison (i don't mean comparison in terms of aesthetics or acting style, but competence in the role).
RE Oscars, certainly Adelle was the only winner, but i was talking about nominations (a massive achievement for Bond's non-technical department). To be clear it was also nominated for best cinematography and score. Both Deakins and Newman came aboard via Mendes and according to Mendes & Craig, Mendes signed up thanks to Craig out right asking him to do it at a party. So one can definitely trace back these Oscar nominations to Craig's involvement in Bond.
As for that anecdote about Mendes not thinking Craig was suitable for Bond, that was when Craig was first offered the role; his friend Mendes suggesting he turn it down. Mendes has been clear that he was wrong on this score and Craig is a fantastic Bond.
My guess is that if not for Craig, then we'd have had a top draw effort from Campbell capably introducing another actor, who would then have been shafted with hacks and ill fitting directors the way Brosnan was. The franchise post-Craig is almost unrecognisable for the better and that's all thanks to the higher caliber talent Craig has attracted.
