I dont mean any of these as criticisms of the last three Bond films, as I think they are excellent, amongst the best of the series and I wouldnt change them. That said I really think some things have well and truly ran their course:
1. No more "trying not to be a traditional Bond film but then having huge homages to celebrate being a Bond film". We dont need references to old films like the Goldfinger car or the golden girl or teasing with a part of the Bond theme before leading into something else, or making in-jokes about the lack of gadgets, just put the gunbarrel at the start, use the Bond theme in an action sequence, use the classic lines. have some cool gadgets, Celebrate it being a Bond film by, well, being a Bond film.
2. No more "personal" issues. No more studying of Bond's psyche. No more internal MI6 drama.
3. A happy ending with Bond getting the girl. I think everyone will be pretty peeved at a fourth ending with someone dying and Bond not getting the girl in a row.
4. Humour. Despite what his critics say (and what he himself has said) Daniel Craig is actually excellent at humour. The dry wit, the off the cuff remarks, Daniel does it as well as Connery when they give him the chance, but its all too rare when they do. I'd like to see a lot more of it in the next film. I think Casino Royale did it pretty well, and parts of Skyfall but I'd like to see more
5. A normal mission. For the first time in about 6 movies.
6. A BIG villain. With a cool lair, and henchmen, and a real threat to the world.
7. Tying up the Quantum loose ends. They are a branch of SPECTRE of something like that.
8. A somewhat slower Thunderball type storyline instead of racing from location to location, from action scene to action scene.
9. Bond leading a commando assault on a villains compound. We havent had that in a LONG time.
10. It'd be nice to see Bond in his naval uniform.

I agree with alot of this.
The reason they have gone on so many revenge-based adventures recently is because of the change in directors and also I honestly believe they have forgotten how many they've done in a row.
At the same time, they think the fans want to see revenge, Bond's pysche, personal issues and MI6's internal issues because each movie is a success.
