Although, I can't rank it as the worst of the Craig Bonds as Quantum Of Solace was a such a boring, pointless snoozefest that all I remember is the endgame revolving around some greasy Mexican General wanting to overthrow his government. Yaaaaawn.
Spectre, for all its WTF moments had more style (and an actually interesting plot, even if it was buried and incomprehensible for the most part.)
Really, the weirdest part of the movie is the fact that they kept restating themes and plot points that had been much better conveyed in Skyfall. Mind you, if I was following one of the best Bond movies ever made, I'd probably want to crib from it too.
