These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

In this film Bond faces off against what would be the first in a long line of burly blonde Aryan looking henchmen in the form of Donald "Red" Grant. A little less than 50 years after this film was made the world was given a blonde James Bond (in contrast to the usual dark haired Bonds) in Daniel Craig and darn if they don't look similiar.
Moral Event Horizon: For most of the film, Grant appears to simply be a professional doing his work. Then he and Bond finally meet and we see what a twisted bastard he really is.
"My orders are to kill you and deliver the Lektor. How I do it's my business. It'll be slow and painful. The first shot won't kill you. Nor the second. Nor even the third. Not until you crawl over here and kiss my foot!"
Not so Mundane Made Awesome: Klebb trying to kill Bond by kicking him in the crotch with her poison tipped shoe while he holds her at bay with a chair.
Special Effect Failure: The actor playing Kerim Bey dabs his arm with a red sponge to simulate being shot during the gypsy camp fight.
Tear Jerker: In-Universe: Karim's death (which pisses off Bond). Meta: Pedro Amerdantriz (Karim's actor) was dying of cancer during filming, and on various scenes he couldn't walk (the running Bey, Bond and Tatiana do through the Istambul market was done with a body double for Karim).
Nausea Fuel: Fleming's extremely detailed description of what it feels like to be shot in the heart.
Tear Jerker: The chapter "Out of Danger," where Bond has to break the news of Kerim's death to his son and M.
Values Dissonance: Kerim's kidnapping, imprisoning, and attempting to brainwash a woman into loving him in his backstory is portrayed as a mere "youthful indiscretion" that the Service quickly straightened out of him, rather than the serious crime it would be extremely difficult to redeem oneself from that it would be seen as today. This can definitely hamper modern readers' sympathy for Kerim.
Bond and Tatiana telling Domestic Abuse jokes. Even as playful banter it's doubtful this would fly today outside of a Black Comedy.
