Best Bond ever?
For me it's still Sean Connery. Connery was not only the template for all the other Bond's that followed, his Bond, with the swagger, the whole "don't mess with you or i'll bitch-slap you so hard you'll be pulling your teeth from outta your ass" attitude, became the template for all the action heroes that followed, from Dirty Harry to Rambo, Indiana Jones to Beatrix Kiddo.
For me, the best Bond film, well, I always like to compare it in the context of when it was made and in what spirit.
So, for me, each generation of Bond films, each actor who portrayed him, brought something unique and different, reflecting the sensibilities of the time.
During the Connery era, my favorite film is Goldfinger, it had the best song, the best villain, the best sidekick, the best dialogue "You expect me to talk?" said Bond, "No Mr. Bond, I expect you to die!" and of course, it had Pussy Galore.
My favorite Roger Moore era Bond film was "Live and Let Die." It had the crazy idea of mixing a Bond film with a blackxploitation flick and "Smokey and the Bandit." It was wacky fun and I loved it. It also had Jane Seymour as the most beautiful Bond girl ever. And then there's the Paul Mcartney theme song.
Of the Brosnan era films, the best for me was Goldeneye. It was dark, edgy and just had a really cool vibe.
Poor Dalton and Lazenby, they didn't have enough time to make their marks on the franchise. There are people who say that Her Majesty's Secret Service is one of the best of the Bond films and I have a hard time disagreeing, since it has the most powerful plot twists in the Bond series, and Dalton looks the part, he just didn't have the chance to earn the part.
As for Daniel Craig, he's a completely different beast compared to all of the previous Bonds: he doesn't have Connery's confidence, neither does he have Moore's charisma nor Brosnan's good looks.
If you asked me, he's got more in common with Jason Bourne and Jack Bauer - Bourne's low-key performance mixed with Jack Bauer's cold and cruel efficiency (shit, he smashed through walls and used a urinal as a weapon for god's sake).
And the film? Comparing it to Connery's films, or Roger Moore's or Connery's is like me comparing a Batman Comic Book from 1963 to a Batman comic book from 2006 -
It was a different time with different rules, different standards, different styles. It's useless making comparisons.
Just remember that the Bond films of each decade defined cool manliness and heroism during each of their times.
