Dr. No finds Sean Connery as a heroic spy named Bond.
James Bond
007 to his comrades.
While this is in the stage of Bond movies being spy movies, there is a hint of the extravagant classic films that follow.
We don't quite get too many exotic locales, but we get a hint of them, and a hint of the beautiful women and of Bond's morality in a world of hate.
Bond kills to stop killers. There's actual morality in his violence.
Ursula Andress is quite striking. She isn't the hottest of the babes who appeared in Bond movies, but she is the hottest blonde woman. It helps that they sprayed a deep tan over her body, because in those days, lighting was the enemy of the fair complexion people.
Unlike most Bond villains, we rarely see Dr. No. He's more of an enigma, but an evil one who must be disposed of for the good of humanity.
Can Bond eliminate him? Hmm?
