Author's Saving Throw: An example where, ironically, the creators were widely agreed to have addressed the biggest complaint of the previous film, while messing up everything else. Bringing back Sean Connery was welcomed by fans who didn't take to George Lazenby's version in On Her Majesty's Secret Service, but the more mature and nuanced storyline of that film was jettisoned in favour of something far Denser and Wackier. This means that On Her Majesty's Secret Service is still seen by many as the pinnacle of the entire Bond franchise, with Lazenby's performance still being the main point of contention, while this film is seen as one of the weakest in the franchise, despite starring the Bond actor generally considered the most popular one.
Broken Base: Not the film itself (which is generally agreed to be the weakest of the Connery era, and the first serious misfire in the franchise), but rather, the film's decision to be the first to go into full-blown camp. A good portion of the fanbase considers this one way the franchise was Growing the Beard for injecting more humour into the series. For the other fans, it's something they'll never let people forget about this film.
Ensemble Dark Horse: Mr. Wint and Mr. Kidd are among the most popular henchmen of the series, standing out for their witty banter and for their gruesome yet creative methods of dispatching their victims. They manage to be both menacing and genuinely funny at the same time. Various shows have parodied the characters and there's even a jewelry store in London named after them.
Genius Bonus: Bond's line, "Alimentary, my dear Leiter" when Leiter is searching for the diamonds in Peter Franks's coffin almost didn't make it into the film. The line refers to the alimentary canal, another name for the gastrointestinal tract, which terminates in...well, you know what. Bond is basically doing a one-liner about how he hid the diamonds on Franks's body where the sun doesn't shine. Apparently, Albert R. Broccoli demanded that screenwriter Tom Mankiewicz remove the line for fear that nobody would get the joke.
Harsher in Hindsight: Bond's line "Well it's just proves no one's indestructible" following killing Peter Franks and switching their identities once Tiffany Case inspects Franks' corpse becomes much sadder in light of Sean Connery's passing in his sleep on Halloween 2020 and the fact his widow revealed he was suffering from dementia.
Hilarious in Hindsight: Plenty's question, "you're not a knight or anything like that, are you?", to which he replies, "no, a mere commoner." Sean Connery was knighted almost three decades later.
Ho Yay: Mr. Wint and Mr. Kidd. The movie suggests that they are a couple, especially in the scene where one of them gets jealous when the other praises Tiffany's physical beauty.
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.
As terrible as his death is, the Chinese soldier's expression when the Kill Sat's beam hits him is pretty goofy.
The entire scene of Bond taking a beating by "Bambi" and "Thumper".
Ernst Stavro Blofeld dressed in drag.
Tiffany Case brings a lot of it to the table, particularly her rather embarrassing Fight Scene Failure in the climax where, clad in a bikini she fires a machine gun in the air while covering Bond, sending herself skittering backwards until she falls off the platform.
Narm Charm: Bond making out with himself is pretty convincingly shot. Its dumb as hell, but about as well done as it can be.
Older Than They Think: Many fans complained that Blofeld had a full head of hair in this movie instead of his iconic bald appearance of the previous two films. In fact, Blofeld did have hair during his appearances in From Russia with Love and Thunderball, though it's difficult to see due to his face being obscured in those films. On top of that, the literary version was also described with an appearance close to that of Charles Gray in this film; in fact, the only reason why the screen Blofeld was ever bald was that Donald Pleasence happened to be bald himself.
Charles Gray's interpretation of Blofeld is the least popular incarnation of the character to date, being much less menacing than his predecessors.
Norman Burton as Felix Leiter, who comes across as being far more bad-tempered and useless than his previous appearances. It doesn't help that this comes right before David Hedison's version in the next movie, which (at least until Jeffrey Wright came along in the Daniel Craig films) was widely considered the most popular incarnation of Leiter, especially since he got to reprise the role (the only one to do so before Wright himself) in Licence to Kill.
The Scrappy: Tiffany Case, who very quickly becomes a Damsel Scrappy as she comes to rely on Bond to save her hide on one too many occasions.
Sequelitis: It's widely considered Connery's weakest and among the low points of the series for its campy tone, cheap, lousy effects and delirious plot.
Signature Scene: The car chase through the streets of Las Vegas is considered by many fans to be the best scene in the film.
Special Effect Failure: Connery's increased salary for the movie meant that a cheaper effects company had to be used to cut costs.
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.
During the chase through the Las Vegas Strip, Bond drives his Mustang through a narrow ally on the two wheels of his right side, only to exit the alley on the wheels of his left side. Chalk this one up to bad editing, one which the filmmakers attempted to rectify by simply flipping the shot of Bond and Tiffany inside the car, making it look like the car somehow managed to flip in the narrow alley.
The Kill Sat itself, which somehow manages to look worse and worse in each shot. In the shots of the rocket launching and separating it actually looks decent, at about the standards of the similar sequences from You Only Live Twice. When the satellite sheds its outer casing and fully deploys, it looks like something you'd see in a cheaper episode of Thunderbirds. By the time it takes out a Chinese military base, the effects standard has dropped to being barely above a contemporary episode of Doctor Who.
As terrifying as the scene of Mr. Kidd burning alive is, one can clearly make out Putter Smith's heavy fire retardant gloves as he is set alight. Moments later, when Mr. Wint is blown up by his own bomb, none of his remains can be seen falling into the water.
James plays with Tiffany's genuine fear of being locked up for pure kicks at times.
Women in general really aren't treated or presented well in this movie. Plenty O'Toole is just there to oogle and to die. Tiffany Chase turns into a bozo after banging Bond. Bambi & Thumper start off as an exception with their ability to fight, overpower and pummel Bond but are easily made useless once they end up in the pool.
Blofeld locks billionaire Willard Whyte up in one of his penthouses, takes his empire and his identity, and places his super-villain base somewhere in North America, disguised as one of Whyte's many oil rigs. You'd Expect: Blofeld to put it somewhere in the middle of the country, where it won't stand out. Instead: He places it on the Baja peninsula, where Bond and Whyte spot it almost instantly.
Given that Blofeld's only motives are to get rich and then wipe his record to be able to enjoy his fortune, he could have stopped right after stealing Whyte's identity: Whyte has all the money he could ever spend on himself, has no criminal record, and since nobody not working for Blofeld knows about the replacement, all he has to do to achieve his final goal is sit back and enjoy his stolen fortune.
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 white Modesty Towel, 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.
What Do You Mean, It's Not for Kids?: Two baddies slowly drowning in mud. Also Mr. Wint and Mr. Kidd murdering Lord knows how many people (including Plenty O'Toole, who wasn't even involved in the evil plan, simply because she was in Tiffany Case's house at the wrong time).
Charles Gray as an unexplainably fully-haired Blofeld, with a "proper English genleman" voice rather comparable to M's and Q's though it can be argued those changes fit the film's decidedly more playful take on the character. Even Guy Hamilton felt that Gray was "not ideal casting".
Norman Burton as Felix Leiter, who was considered to be too old and physically unconvincing as Bond's American counterpart.
Sammy Davis Jr., which may be why his rather meaningless cameo in the film was cut from the final product.
WTH, Costuming Department?: Tiffany Case's red hair, which is considerably less alluring than her brown wig she had donned upon her introduction to Bond.
Nausea Fuel: Fleming lovingly draws out every single detail of how disgusting the mud baths at Saratoga (not to mention its customers) are. It's topped off with one of the most disturbing torture scenes in the book, if not the whole series.
The Scrappy: Jack and Seraffimo are easily the least liked of Fleming's main villains, being completely mundane gangsters with completely mundane motives. It's probably telling that they're the only Fleming Big Bads never to have been adapted to film.
