Honestly, I have mixed feelings. Casino was great, and I even loved Quantum. However Skyfall got a little too ridiculous at times and Spectre had a twist straight out of Austin Powers. At the same time both had great moments.
In General I have the following idea
Keep Casino Royale:
Modify Quantum: Bond’s relationship with Camille stays and the theme of him trying to face his demons is there, but it takes center stage. Rather than the water scheme Bond’s quest for vengeance takes center stage. In the end Bond gets over his grief and gets as much peace as he can, but Mr White escapes. This plays a role later.
Bridge Film: Rather than jumping straight to Craig in his older years, we get a more classic standalone Bond Film; this has the typical formula elements but still differs in some ways. We see Bond as a full established career. He’s not quite in the cynical mode we see in Skyfall
Spectre Trilogy: This is a series of movies that chronicles the end of Bond’s career.
Skyfall: Modify it to make Silva’s plan a little less ridiculous. Show that there’s a dark force guiding Silva’s actions. Spectre is rising
Spectre: Overhall the movie; Bond’s connection to Blofeld is that when Quantum fell Blofeld swallowed the remnants, which is what helped him become powerful (making Bond indirectly responsible for Blofeld’s rise to power). Bond manages to thwart nine eyes and we get the start of a war
Final Craig Movie: Spectre and the various intelligence agencies are at war; unfortunately Blofeld is being backed into a corner and quite frankly a snake is most dangerous when it’s cornered. Bond thwarts Blofeld’s attempt to unleash a bioweapon but Blofeld in a final act of cruelty tries to recreate Vesper’s death with adeline but this time Bond is able to save her. Blofeld is defeated and ultimately jailed. Bond retires for good to be with the woman he loves.
