The first five with Sean Connery are all great, with From Russia With Love probably being my favorite of the early flicks. On Her Majesty's Secret Service is quite good too, although I don't particularly care for George Lazenby as Bond. The Roger Moore films are highly inconsistent; The Spy Who Loved Me is quite entertaining, while Moonraker is thoroughly awful. Both Timothy Dalton flicks are dispensable. Pierce Brosnan era...GoldenEye is stellar and stacks up well to the first five with Connery, the other ones are your standard run-of-the-mill Hollywood action, nothing great. Tomorrow Never Dies is quite fun, though, and has one of the series' best villains in Jonathan Pryce.
Which brings me to Casino Royale = greatest Bond flick ever. Everything just comes together so well in this one, and it has by far the best directing and overall filmmaking of any Bond Film. Daniel Craig's interpretation of Bond is also the one that stays most true to the books, which is a big plus. Yes, the concept of having Judi Dench playing M is completely absurd and fucks up the Bond timeline beyond recognition, but I don't give a fuck.

Awesome movie in every single aspect.
That's the answer from a complete and utter Bond nut, mind you. Although there are ones I don't care for at all, I've watched all the movies at least five times each. The first one I've watched upwards of 15 times. GoldenEye and all the ones preceeding it are big pieces of my childhood.
