The James Bond books had lots of continuity. The film series rather savaged this by doing them all completely out of order . . . and of course, you know, having less and less to do with anything that Ian Fleming actually wrote as they went on.
I like that they kept it so Blofeld doesn't recognise Bond in OHMSS, since in the book series they had never met. That film is one of the few that actually keeps true to the source material, which is one of the reasons I'm fond of it. I was able to see it at an art theatre in New York a few years ago with a very appreciative crowd, which was great.
There was some controversy about the colour scheme having been altered in the beginning of the film on the recent remaster, but I took note of this and the blue lighting was definitely there on the 35mm print, though not exactly the same shade or quite as dark. This suggests that the old video transfer is inaccurate and artificially brightened in that scene, which surprised me. It was definitely a somewhat older print, since some of it was scratched and it had the original mono mix (which is far better balanced than the remix even though the sound is harsher), but it didn't seem to have faded or red-shifted at all, so I'm confident that it was a proper rendition of the film's appearance.
I dislike about half of the Bond films because they are so campy and over the top. I have no idea why they kept taking the film series in that direction, but it's often irritating and stupid. My favourites are the ones that take the premise and the character of Bond seriously, and these are usually the ones that adhere more closely to the spirit of Ian Fleming's creation. Even among the better films, few of them really represent Bond himself being like the literary character, but the old movie persona is so ingrained in the popular consciousness that most people can't think of him any other way.
Since they effectively rebooted the series with Casino Royale, which is the first of the books, I really think they should have tried to do it properly this time and do them all, in order and more like the original stories while keeping the modern setting. Doesn't seem like that's going to happen, though.
