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.
Jerry Goldsmith, people. This is especially true for Rambo: First Blood Part II (Goldsmith quipped that this score paid for his house), even unto the Animated Adaptation being liberally tracked with the film's score.
Colonel Zaysen from Rambo 3 destroys Afghan villages and kills innocent people, including women and children, with mines, bio-weapons, and other evil stuff for no reason at all, even when said people did nothing at all.
Major Tint from Rambo 4 manages to be the worst antagonist that has appeared in the entire franchise. He's an Ax-Crazy military-leader who forces villagers to walk into mine-infested marshes, and he and his men shoot and dismember entire families (including childrens and babies) of villages. Also, he threatened to cut out the tongues of anyone who tried to stop his indoctrinating teenage boys into his army, as well as threatening to feed them their intestines. To add even more monstrosity, he's a depraved pedophile and has hostages in inhumane conditions.
Germans Love David Hasselhoff: Interestingly, the Rambo movies are very popular in Japan. To the extent that there's a Rambo arcade game in Japan that has never been released in the United States.
Harsher in Hindsight: Rambo III's foreword says that the movie is dedicated to the mujaheddin of Afghanistan. The mujaheddin, a catch-all term for "holy" warriors resisting the Soviets, included what would become Al Qaeda and the Taliban.
Heartwarming Moments: The end of the fourth movie has Rambo at long last going home, 30+ years after the end of the war that took him away from it, and looking behind him at the long road he's finally finished walking. The scene was poignant enough to single-handedly make everyone decide that Rambo V was a bad idea.
A truly bizarre example - the first ever review of the fourth Rambo movie went: "A glorious movie. The villains are obvious, the hero never speaks, and everybody dies." Who gave this review? Lieutenant Worf, in a Star Trek: The Next GenerationExpanded Universe novel, which was written about fifteen years before the movie was filmed. It's surprisingly accurate.
Iconic Character, Forgotten Title: The first movie is called First Blood, despite people simply calling it Rambo. This is probably why the fourth film was simply called Rambo, but it ironically made things worse.
Rambo's motto from the fourth film - "Live For Nothing, or Die For Something" - has become the rallying battlecry for Karen Warriors in real life. Stallone has called this one of the things in his life that he's most proud of.
NOTHING IS OVER! NOTHING! from the first film. More specifically, Stallone's melodramatic and almost incomprehensible delivery of the whole speech.
The "nuclear-tipped arrows" from First Blood pt II.
"Being a Rambo" became a term to describe anyone who are or try to be a One-Man Army.
Art Galt crosses it when he recklessly shoots at Rambo without giving a shit about his own safety or that of the rest of the police department and actually threatens to kill the chopper pilot if he doesn't fly the chopper right.
In the second film, Murdock crosses it when he orders the mission aborted and convinces Erickson to threaten Colonel Trautman with a shotgun if he has him press any further with his chopper.
Narm: From First Blood sobbing Johnny Rambo recounts his traumatic 'Nam experience, (making even hardass Richard Crenna's lip tremble) is this if it's not a Tear Jerker; the enunciation leaves something to be desired.
There's also David Caruso's screams of pain when he gets stabbed in the leg.
The part when the asshole deputy Art Galt dies has a bit of Fridge Humor: He's falling in slow motion but screaming at regular speed. So, does that mean he was squealing like a chipmunk on the way down?
From Rambo 4, Rambo's facial expression after being grazed by a bullet. My god, just... you know chill. He's not living for anything if he keeps shaking the camera around like that.
That face comes built in (it was caused by forceps damage when he was born), so expect some narm any time Stallone yells.
"They would have RAPED her 50 times, and cut all your FUCKIN' HEADS OFF! WHO ARE YOU?! WHOUHANNYOYOU!?"
It's hard not to laugh when Rambo rams his tank into the Big Bad's helicopter in the finale of Rambo 3 because of Stallone's trademark idiotic battle cry.
The Problem with Licensed Games: ... But unfortunately, most of the Rambo tie-in games aren't very good, most infamously the NES game adaptation. The 2014 game simply titled Rambo: The Video Game was heavily criticized for its dated rail shooter gameplay and graphics, while making a mess out of the first movie's plot (such as a scene where Rambo drives a truck into a gas station, causing it to explode, and him gunning down cops with a machine gun which never happened in First Blood). The game garnered reviews that ranged from So Bad, It's Horrible to So Okay, It's Average.
Sequel Displacement: The sequels are definitely more well known than the first film. Take, for instance, the fact that it was titled First Blood and by the third film, it was called Rambo III, or the fact that Rambo is known for high body counts, even though the grand total of dead bodies in the first film is a single Asshole Victim which Rambo didn't even kill on purpose.
