There’s a lot of issues I have with Quantum Of Solace but unveiling Quantum as this big, bad, evil organization and then just totally dropping it for the next two movies is really bad. Almost unforgivable. The ideas about Quantum being a smaller part of a bigger SPECTRE organization or even saying in SPECTRE that Blofeld had re-named Quantum as SPECTRE would make so much more sense. Or as was previously said, leave the organization nameless–at least for one film. Have Bond learn it the next time around. Keep it even more mysterious and sinister than it already was.
Of course, when the filmmakers came up with Quantum, at the time they didn’t have the rights to Blofeld and SPECTRE (or at least weren’t confident enough legally to attempt to use them). Little did they know that they would officially and fully get the rights to both within six years. But dropping the Quantum organization entirely leaves a gaping hole.
Obviously, the Blofeld foster brother thing was complete idiocy and should never have come anywhere near the production. That’s bad TV writing. It would have been far better to have dropped that idea completely and just have him and Bond cross each others’ paths on their various missions and become arch-nemeses as they were in the novels. As Blofeld said, Bond messed with his world by interfering in the Casino Royale business, so he destroyed 007’s regarding Vesper with similar scenarios happening on each succeeding encounter.
