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.
Cry for the Devil: When Scaramanga worked as a child in his father's circus, his only friend was an elephant he took care of. When a policeman shot the elephant, Scaramanga murdered the policeman and so began his life of crime.
Damsel Scrappy: Mary Goodnight is among the least popular girls from the Bond franchise.
Ensemble Darkhorse: Scaramanga is often referred to as a great Bond villain in not so great Bond film.
Foe Yay: Between Bond and Scaramanga, mostly one-sided. Scaramanga may like the ladies, but he also seems to have a bit of a guy crush on Bond, just enough to qualify as Ho Yay.
Freud Was Right: The way Scaramanga caresses Andrea's body with his golden gun.
Hilarious in Hindsight: As Scaramanga shows off his lair to Bond, he tells him that science isn't really his strong point. Years later in the Licensed GameGoldenEye: Rogue Agent, he is quite the opposite, as he is made into an Evil Counterpart of Q, and his job is to come up with the all the cool gadgets for the protagonist. This is actually much closer to his characterization in the novel.
Maud Adams character is killed after having sex with Bond - and specifically because she had sex with Bond, which Scaramanga did not appreciate. Years later Maud Adams played the title character in Octopussy where she thinks that Bond dies horribly after having sex with her, but fortunately he survives.
Idiot Plot: Much of the movie, particularly the final third, could've been avoided if Goodnight wasn't so stupid. Also, the entire sequence in Beirut — why did Bond need the slug that killed 002 when he already had an intact bullet sent to him? He could have gone straight to Macau, and the film likely would have been better.
Lulu's completely insane title song straddles the line between this and Narm Charm.
Bond swallowing the golden slug that the belly dancer used as a charm, and then having to have his stomach pumped to retrieve the bullet to show to Q back in London. An entirely useless sequence, and probably the most laughably idiotic thing to happen to Bond.
Padding: The film is prolonged by pointless meandering in a few cases. For example, why Bond had to get the bullet in Beirut when he had the one sent to him, the Kung Fu scene and its following canal chase etc.
Stop Helping Me!: Goodnight blocks Bond's taxi, gets kidnapped uselessly trying to plant an unnecessary tracking bug while carrying the mission critical MacGuffin, causes a chain reaction by knocking out the man keeping watch on her, and triggers the solar beam where Bond is working.
Take That, Scrappy!: In his last scene, Pepper is arrested by the Thai police, and as far as anyone knows, he's still in Thai prison.
They Wasted a Perfectly Good Plot: Sort of. Although the climax of the film is by no means bad, the concept of Bond and Scaramanga having a showdown should have been a LOT more suspenseful and dramatic. Instead, Scaramanga spends almost the entire duel running away and leaving Bond to traverse his funhouse, before being shot before he manages to even pull the trigger.
Vindicated by History: A very minor example. Although it still is regarded as cringe-inducingly camp at times, the film's theme of duality has been commended in recent years, as has its villain, Moore's performance, and even its pace, despite the arguable Padding.
They Wasted a Perfectly Good Plot: A brainwashed James Bond working for Soviet Union is an interesting story itself, but it is quickly undone so that he can be put against Scaramanga, who is essentially just a glorified thug.
