Thunderball is everything one would expect from classic James Bond as there are enough beautiful women, gadgets, and action for everyone. However, the film as it stands today is a bit drawn out and lacks the intensity of some other Bond films, such as Goldfinger or Dr. No.
While these points are certainly the heart and soul of any classic James Bond adventure there are holes in this particular boat which sometimes make it feel a but dead in the water.
The film was one of Sean Connery's favorite Bond films to work on as well as being a critical success, with Thunderball easily overtaking the worldwide cinema totals of the first two James Bond films.
