I mean really the best films are those directed by Terence Young (the first two and Thunderball) and I'll maybe add You Only Live Twice because of how bonkers and defining it is (crazy space science and hidden giant base full of goons). Goldfinger for instance is dragged down quite a bit by its pace and direction and despite every else being great it is a bit of a bore. I'm not an expert but a lot is owed to the craftsmanship of the steady and talented team that made the original run, notably production designer Ken Adam. And of course John Barry soundtracks.
Have a lot of affection for Roger Moore but while he was always great the only real highlights are The Spy Who Loved Me (where Moore's Bond is suitably brutal in the first half) and Moonraker (it's super goofy, corny and a bit desperate in aping the successes of its time but the production design and SFX are awesome and the villain memorable) and really it is just retreads of the Only Live Twice formula. The Man with the Golden Gun deserves a watch for how cringily mysoginistic it gets and the bottom of the barrel comedy and writing. Also C.Lee and the midget from Fantastic Island. But the Moore films were very much played on his comedic performances and should be appreciated for that even if they also got cornier with age. I guess the ski scenes are a good shortcut to define them : impressive in their own right for the stunt work but too samey and formulaic.
On Her Majesty... doesn't hold up well but it's crazy and different enough to hold its own. Great tune and Diana Rigg is awesome.
Not a big fan of Dalton films but I like the bits where it goes slightly absurd with an Avengers (The British TV show) bent. There's a part where someone is infiltrating a poshy house and cooks and butlers are all secret agents proficient at close combat (a bit Bourne-ish too).
Brosnan was really just a C grade knock off of a Connery and Moore amalgamation. I think Goldeneye is hokey, by the numbers and has terrible music (save for Turner song) and mostly overestimated for reviving the franchise (I suspect it's a bit of a marketing talking point that has been massaged by the producers, we get some canned discussion like that at every actor change). Tomorrow... is decent, Die Another Day is a mediocre greatest hits compilation and The World... is really really bad.
Casino Royale is OK, I guess. I'm not big into it and I don't buy the whole rejuvenation argument. QoS has issues (directing and editing) but the backlash was a bit much. Skyfall would be pretty good if not for the last act which is by far the most horrendous thing they could do with the character (grafting the same boring shit of daddy and mommy issues every other generic character have these days) and getting all weepy over Judi Dench (Bernard Lee is the iconic M, fuck you Eon).
And the original Casino Royale is boring as fuck, but this type of sixties comedy never did anything for me. Watch it for some of the clever parody/meta ideas and the cast, I guess.
Never Say Never Again is sort of decently mediocre but really why bother when you can watch Thunderball ?
