Firstly, please go back and read my post. At no point did I refer to OHMSS as a flop. My worRAB were : "...and the movie, for a Bond film, performed poorly."
I think this is fair considering that, in inflation adjusted box office gross, OHMSS reached a worldwide sum of $317 million. Thunderball, incidentally clocking in at just ten minutes shorter, made $807 million. Only two Bond movies have performed worse than OHMSS on a worldwide scale; A View to a Kill and Licence to Kill. When a film makes half as much as the preceeding film in the franchise (You Only Live Twice; twenty minutes shorter) it's a disappointment.
Don't let any of this put newcomers off. OHMSS is a solid Bond movie.
This is a bizarre statement. I've read Fleming and I'm sure you, like me, have come to the conclusion that the Bond in the novels shares very little in common with the Bond that we see in many of the movies. To say that you can't fully appreciate something just because you haven't experienced it in an entirely different medium represents an extreme case of snobbery.
