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.
YMMV: King Kong
Awesome Music: The "Jungle Dance" music from the original. Also used as the background music to the "Eighth Wonder of the World" show in the 2005 remake.
The 1933 soundtrack is still well regarded by both musicians and viewers.
The sudden giant snake in the 70s version. If dinosaurs/other giant animals showed up earlier it wouldn't be so odd.
Don Simpson's 1993 comic, adapted from the Delos W. Lovelace novelization, originally had a scene it where Kong destroys the Hindenburg. It got cut after Simpson decided it was in poor taste and too bizarre.
Complete Monster: The creatures living in the Spider Pit, per this analysis from Filmfax Magazine: "The denizens of the spider pit are the polar opposite of [the rest of the film's] primal fantasy. They live in darkness, in the dim places where the sun never quite reaches. While the dinosaurs hunt and graze for their livelihoods, these creatures lie in wait, ensnaring their prey or scrabbling for the leavings that trickle down to them from above. They are the carrion-eaters, wallowing in corruption even as they feed off it."
Designated Hero: Jack in the 2005 version. Most of the crew's deaths can be traced back to his obsession with saving Ann, and all the while, he constantly gets upstaged by both the titular ape and even the snooty actor he didn't like.
Denham in the original. The entire trip is his idea, as is the choice to bring the ape back to New York, where it promptly wreaks havoc and causes more deaths but he is never called out for his actions.
Fair for Its Day: Yes the original Charlie the Cook is pretty cringe-worthy but this is the 1930s and the guy is the first to notice Ann is missing, is willing to help go after Ann, and brave enough to swing his cleaver at a very angry dinosaur in the sequel. Plus in the same sequel he isn't excluded from the spoilers either.
First Installment Wins: While there have been many sequels and remakes, the original 1933 film is the version most often spoken of by fans.
It Was His Sled: There aren't too many people who don't know how this story turns out.
Magnificent Bastard: Dino De Laurentis is a meta example. During the film's production he knew damn well that no one would believe in a giant 40 foot gorilla and would constantly look for mistakes to make the illusion even more fake. So what does he do? Well he instead built a giant 40 foot robot Kong and exclaimed that the robot was going to be the monkey, not revealing that the robot was only going to be in the movie for a couple of seconds. And when critics saw the movie, they basically tried to show a distinction between the robot and the giant ape suit. The kicker? They got the comparisons wrong. So De Laurentis pretty much fooled people into believing an illusion with another illusion.
Misaimed Fandom: For the 1933 Kong at least, to some extent. He does kill quite a few otherwise innocent people on both Skull Island and in New York when he breaks loose. He was meant to be sympathetic, but not to the extent that you should ignore his destructive qualities.
Son of Kong, while inferior to the first film by far, still manages to entertain. It helps that the cast has three major returns in it (Mr. Denham, the Skipper and Ethnic Scrappy Charlie the Cook) and Willis O'Brian returns for the special effects.
Special Effect Failure: The Stop Motion used for Kong and the dinosaurs in the original version to modern viewers who do not begin to comprehend the effort or complexity of what was done focusing on ther layman assesment of "It looks like clay". For the time, they were the best special effects around, some shots still astound modern special effects artists with their seemlessness and complexity. But it's doubly impressive considering that the alternative would have been lizards in makeup. The King Kong Suit and half-second of stop motion in King Kong vs. Godzilla however, are universally seen as poor. Doesn't stop people from enjoyingit, though.
The snake from the 1976 version could also qualify, looking very stiff, robotic, and lifeless compared to the fairly realistic animatronic face and hands built into the Kong suit.
On the subject of Kong '76, there the the very literal failure though the highly publicized full-scale mechanical Kong armature, designed by Carlo Rambaldi. Leading to makeup legend Rick Baker designing and donning the ape suit used for 95% of the movie. The mechanical Kong was only in one scene -his New York unveiling- and boy, can you tell.
Even the version of the Kong arm which was used in the (now retired) Universal theme park attraction was notoriously fake-looking.
They did build a to-scale animatronic of Kong's head and shoulders for the 1933 film. It has several quick appearances, the most notable being Kong's unveiling in new York and during his rampage in the native village (the close-ups where a villager is in his mouth). Though it was pretty motionless (only the eyes and mouth could move, and limited at that), it still worked fairly well.
Too Cool to Live: The Cook played by Andy Serkis in 2005 version. What's worse is the method he dies. He gets attacked by large worms that eat him limb by limb digesting him in a slow and painful manner.
Unfortunate Implications: The primitive natives. And the relationship between Kong and his girl—especially with regard to her somewhat forceful adoption by him—has been compared to a relationship between a black man and a Nordic woman. And it's not a favorable comparison. Of course, the connection is purely apocryphal, as it was believed at the time that gorillas would actually rape women◊, so it's probably not meant as a metaphor.
Merian Cooper, the director, strenuously argued against a sexual interpretation of Kong's fascination with Ann Darrow; he saw it as Kong simply playing with a toy.
The 2005 version goes for less of a sexual relationship and more of a Koko and kittens one.
The infamous "Beauty killed the Beast" line at the end of both films. Apparently only a white, Western woman is beautiful enough to have an effect on Kong even though he spent his life surrounded by dark-skinned people native to his island and, if anything, should have adopted their standards of beauty.
This actually can be considered Fridge Brilliance: if Kong views the people sacrificed to him as pets or toys, he may become obsessed with the unique-looking, unusually bright-coloured one.
The 2005 version also tries to remedy this by having Ann survive by using her circus act, intriguing Kong because no one's tried to appease him before.
Visual Effects of Awesome: For 1933, anyway. The stop-motion effects were so impressive they got a kid named Ray Harryhausen interested in making that a career. There are still cinemaphiles and effects experts impressed with how Willis O'Brien made his effects.
The 2005 film has amazing CGI/motion capture effects. It rightfully won the Oscar for Visual Effects (it also won for Sound Mixing and Sound Editing and was also nominated for Art Direction)
What Do You Mean, It's Not for Kids?: While the 2005 version is probably a bigger target, even the original 1933 version is subject to this. Not only are there a lot of death scenes, they're surprisingly brutal! The stereotypical natives and the scene where Kong undresses Ann do not help.
