Quantum of Solace was very poor; not a patch on Casino Royale IMO. Among my favourites are;
Goldfinger
Dr No
Thunderball
Live and Let Die
A View to a Kill
Goldeneye
And a bit of controversy here; On Her Majesty's Secret Service. I know George Lazenby got slaughtered by the critics for his acting and got the sack by Cubby Broccoli after one film, but if you can look past him, it isn't THAT bad a film. Would have liked to have seen Connery in that film.
