I hate Doctor No. I quite like the villian, but the film is just way too slow. Plus the title sequence is one of the worst ever, IMO.
I love Dr. No -- the first 3 Bond films are, IMO and many others, classics.
What you might consider is that in 1962 no one had made a film like Dr. No - North By Northwest is probably the closest in terms of the style, tone, humour, action set pieces.
Maurice Binder's titles were unique and his graphics, the use of the dots, the inspired gun-barrel, the silhouettes and bold blocks of colour were very fresh and established iconic images that are still being re-worked to this day, just look at the moving dots in the QOS titles.
The pace may seem slow to some by today's standards, but in '62 Dr. No was considered a very fast moving picture - Peter Hunt's razor sharp, bold editing was way ahead of its time. Some critics even thought the film was too fast.
Bond's introduction in the casino is wonderful. Connery is terrific; and would only get better in the next 3 films. The film is beautifully photographed, has tremendous atmosphere and is very well cast. Great set design by Ken Adam which is unlike any other film at that point in time.
In '62 Dr. No was pretty ground breaking stuff and it made a huge impact on the action/thriller genre. I know people who saw it back then in the first weeks of its release and they were simply blown away by it.
It can be argued that we can only judge a film (or any art, book, stage play, music etc.) by how we see or experience it NOW, but I strongly disagree. IMO, everything must be seen in context; the history/the past mustn't be ignored otherwise all those great classics will be lost on the next generations and that would be a terrible shame.
