The films are just escapist nonsense but for their kind rather well made and for a mass market. I read the books many years ago and have always found the films very disappointing. They seemed to get even worse and more ridiculous as the series went on.
First bond book written 1953 and first film Dr No 1962.
Yes the 12 novels and 2 short story collections are much better than the films. if you enjoy them try reading The Saint books by Leslie Charteris the TV series was poor in comparison and the films even worse.
