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.
Similarly, did Terk not want Tarzan hanging around with her and the other gorilla children because she was embarrassed by him, or because she knew they didn't like him and didn't want him to feel like any more of an outcast than he already did?
Big Lipped Alligator Moment: "Trashing the Camp." Other than letting Jane learn that Tarzan is part of the gorilla community, this scene has no purpose other than to show off a cool scat jam written by Phil Collins.
The commentary reveals that the directors considered cutting it several times, but it was a big hit with kids in the test audiences, so it was kept in.
Fair for Its Day: The books are rife with Burroughs' well-meant ethnocentricity and sexism. Burroughs repeatedly mentions the vicious and exploitative treatment the African natives received at the hands of white men, and attributes at least part of their bloodthirst to a desire for revenge. He usually finds something to praise about his various ethnic characters, even if it might be in a way that would be extremely offensive today. Jane may not be an Action Girl (let's not be ridiculous!), but she's intelligent and remains level-headed no matter how dire the emergency.
Germans Love David Hasselhoff: Thanks in no small part to the fact that the hugely popular Ákos Kovács did the songs for the Hungarian dub of the movie, this film's music is immensely popular in Hungary, enough so that Ákos regularly performs them at mainstream concerts.
Moral Event Horizon: Clayton from the Disney version crosses this when he shoots Kerchak, Tarzan's adoptive father, then, much like Gaston, tries to kill Tarzan after Tarzan spares him, resulting in a gruesome Karmic Death afterward.
Most Wonderful Sound: When Tarzan first lets loose his signature yell you know the awesomeness has only begun.
Viewer Gender Confusion: Sabor and Terk, both of whom are female, though Terk was apparently based off a male character. It doesn't help that in the stage musical Terk is now male. Terk is at least alleviated a little when you know she was voiced by a woman, but Sabor doesn't even have a voice to go by.
