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. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ensemble Darkhorse: Mr. Wint and Mr. Kidd. Various shows have parodied the characters and there's even a jewelry store in London named after them.
Fridge Brilliance: The two fakes both refer to him as 007; the real Blofeld always calls him "Mr Bond". In fact, throughout the series, Blofeld nearly always refers to him as "Bond" (or some variation thereof).
Fridge Logic: Bond uses a voice changing machine to intercept Blofeld's order to Bert Saxby to kill Willard Whyte. But then Saxby still shows up to do the job, making one wonder how he found out about the order.
Blofeld noticed something odd about Saxby's voice. He probably called Saxby back on a hunch.
"Funny Aneurysm" Moment: It was good that Lana Wood (Plenty) and Jill St John (Tiffany) barely had screentime together, given that both women and Robert Wagner allegedly had a falling out over Lana going to the media with her version of the events that led to the drowning death of Natalie Wood.
The sexual humiliation that Plenty endures in Bond's hotel room may not sit well with today's audiences either.
Harsher in Hindsight: On a related note, the one scene that both actresses appeared together in had Tiffany Case go into her house, finding Bond standing by the swimming pool and Plenty drowned in the middle of the pool.
Narm: The fake Blofeld's death in the Whyte House: he's shot in the head with a piton gun, freezes for a second or two in shock, then suddenly flings his arms in the air and topples over.
The Chinese soldier's expression when the Kill Sat's beam hit him.
The horrible dub job in the opening scene, as the actor keeps his mouth wide open but we still hear "Cai...Cai...Cairo!"
Nightmare Fuel: The cremation scene. Getting cremated alive has got to be the most horrific way to die imaginable.
The poor Chinese soldier's death by Kill Sat above.
Plenty being caught almost completely naked.
Sequelitis: It's widely considered Connery's weakest and among the low points of the series for its campy tone and delirious plot.
Special Effect Failure: Connery's increased salary for the movie meant that a cheaper effects company had to be used to cut costs, and it shows with the exploding helicopters at the end and the killsat laser beams and its effects towards the end of the film.
During the chase scene with the moon rover, you can see a wheel rolling on screen just after the rover goes off camera. This is because they crashed the rover.
Values Dissonance: James plays with Tiffany's genuine fear of being locked up for pure kicks at times.
What an Idiot: Willard Whyte has installations all over the place; Alaska, Florida, Maine, Oregon, Texas, Baja — wait, he doesn't have anything in Baja? The villains could've set up anywhere along any coastline, and they choose the one place Whyte knows he doesn't have any property? And then they mark their secret base on Whyte's map?
To be fair, Blofeld didn't think that he would be kicked out of that hotel room, so the map was more or less safe. And Whyte does have property in Baja- Blofeld bought it when impersonating him, so it (semi-)legally belongs to his company.
The biggest problem seems to be not that they used Whyte's name to buy it, but that they built a model oil rig and put it on his giant floor map of property. Nobody exactly comes up to see Whyte, and those who have access to the room and know about the purchase likely wouldn't question the lack of a marker simply because it's not a big deal (and those who have access are probably in on the plot to hold Whyte hostage anyway). Literally the only person who would actually notice them marking their secret base is the person who could blow the lid on the whole operation. Had they not bothered marking the purchase, they'd have had to search every location on the map and give Blofeld all the time in the world to laser cities.
How Plenty O'Toole got herself into her chilling fate, which has been a mystery to fans and viewers for years. Plenty's unfortunate send off was the result of a deleted scene where after getting thrown out of the hotel room and into the pool a soaking wet Plenty, wearing nothing but a towel and carrying her purple high heels (it is not addressed whether or not she still has her iconic transparent pink panties) returns to Bond's hotel room in the hopes of retrieving her clothes and seeing what's happened to him - and is positively outraged to find Bond having sex with Tiffany Case. Before leaving in a huff Plenty rummages through Tiffany's purse and finds her address, so she later went to Tiffany's to get even. It didn't go well for her... A bit of unintentional yet amusing Fridge Horror here is that without this deleted scene one is left with the idea that Plenty possibly had to return to her home WITHOUT her proper clothes.
Values Dissonance: Felix makes a joke about how you can't call a measure of whiskey a "jigger" anymore; now you have to call it a Jegro.
