I now find I just can't watch any of them apart from the Craig ones. I liked how they effectively re-booted the franchise with him and stripped away most of the lame jokes and gadgetry and gave it a grittier, gloomier feel. That said, Quantum isn't very good, despite the presence of the luscious Gemma Arterton. Also, on a good day I can stomach the Dalton ones, Licence To Kill in particular, and maybe one or two Connery ones. The Moores are a no-go area for me!
Quantum, although a bit weak at places works for me as closure to Casino Royale. I have more issues with Spectre to be honest, after having worked hard as you said, to strip always most of the nonsense, I think they fell a bit too much in the Roger Moore era atmosphere. Not a fan of Dalton but License to Kill is imo the best Bond song ever.
I suppose over time we can critize which Bond is better. I've watched every movie, apart from 2 early Connery Bond movies, mainly because I was too young to watch them in the cinema .
I'm sure whoever replaces Craig will have have a lot to live up to. And if he becomes a better Bond, then I'm sure the knives will be out too . I do miss those simple gadgets and the humour of Q..
Hopefully the next one will be a white British bloke. . Unless Craig decides after the next movie that he wants to carry on.
