QoS did good because like most sequels its BOX was showing the confidence and overall enjoyment most still felt about Royale. You'll see a likely good drop for Bond 23 cause even more feel let down by QoS. That is why the CraignotBond folks will be having the last laugh.
So what'll be your excuse when the next Bond movie makes more than $500 million worldwide, which it most certainly will? And how many Bond movies have to make more than $500 million before you admit that the CraigNotBond guys were wrong?
Hey Transformers 2 has made over $300m US domestic, doesn't mean its a quality film. Craig's James Bond isn't quality either and QoS proves that. Posters on this very board are even coming around that Royale doesn't hold up on repeated viewings. More fans see that. Could the next one flop? I doubt it but it could make much less. Less enough to show the studio that fans have soured to this direction and Craig as Bond.
If the next one makes over $500m WW it'll be cause the international market picks up the slack. Bond did not grow its US audience by any significant margin and I see the brand as on the downside for the next one here.
