The trilogy seemed like it was setting up how James became who he was. He hunts down all of these bad guys and wants to avenge the love of his life.

In "Spectre", we learn that James didn't really hunt down these guys as much as Blofeld has been gunning for him. And he gets over Vesper and falls in love with a new girl, throwing away his gun and taking the girl - finally making the choice of having a life over giving his life over to his job. (I mean, she even gets him to order a Dirty Martini!)

The better ending would have been James sending her off. Some "I promised your father I'd keep you safe and you'll never be safe around me." type line so then we have the James Bond we know in love. Instead, they now have to throw in some explanation of what the heck happened to her.

Although, I think this makes it all the easier to wrap up the Craig era and do a mini-reboot with Idris.
