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.

YMMV: Conan the Barbarian (1982)
Adaptation Displacement: John Milius's film is likely what many think about when they hear the name Conan the Barbarian and not the Howard stories. And it's very likely that Conan = Arnold for many people. Anyone who plays Conan gets compared to him. Conan dates back to 1932, older than Superman.
Anvilicious: According to this Overthinking It article the 1980s Conan movies have strong feminist, anti-racist and atheistic themes. On the flip side of that coin, director and co-screenwriter John Milius self-identifies as conservative/libertarian in his personal views, Conan himself is a fiercely independent warrior who eventually becomes a king on his own steam, and the film explicitly shows that there is an afterlife when Valeria briefly comes Back from the Dead.
Awesome Music: Well it does have one of the best movie soundtracks ever made. In fact, there are some music critics who consider this score to be one of the greatest classical music compositions of the 20th century.
Complete Monster: Big BadThulsaDoom starts by slaughtering Conan's village, decapitating Conan's mom while he stands next to her and selling the children as slaves just so that he can obtain weapons of fine steel from the barbarians. Later in the film, he orders a young woman to jump to her death to illustrate how much control he has over his followers before ordering Conan to be crucified. Shortly after that, we find out that he and his followers practice cannibalism. He proceeds to kill Valeria, probably Conan's greatest love in the movie-verse, with a snake arrow. After Rexor and his army's defeat in the Battle of the Mounds, Thulsa coldly tries to do the same thing to the Princess after deeming her no longer useful to him
Memetic Mutation: Even people who haven't seen the movie can quote the "what is best in life?" scene (although the original is attributed to the real Ghengis Khan, an expy of which is in the scene).
Narm Charm: Although many of the quieter scenes are actually well done, a good portion of the movie is narm. Awesome, glorious narm that fits both the setting and the story like a glove, somehow managing to be incredibly moving when in many other movies it would be just plain ol' Narm without any of the charm.
The camel who gets punched out (twice, even!) in both this movie and its sequel.
Conan's father only gets one scene and one speech. It's all he needs.
Unfortunate Implications: As Roger Ebert noted as early as the film's release: Conan becomes a Germanic superman with a black arch-enemy. As hinted by his name, the original Conan was Celtic (or rather, his people were ancestors of the Celts) and in his original stories he had no arch-enemy at all. Also, Thulsa Doom has blue eyes and is swarthy rather than truly black. And he's just the Big Bad of the movie, not a recurring arch-enemy.
Thulsa Doom's snake cult members resemble hippies and/or followers of New Age or New Religious Movements.
It should be noted that in the original stories, Conan actually spent most of his adult life alongside the Aesir raiders in the North, who are a race in Howard's mythos that are an analogue to the Vikings. He took to their ways more eagerly than he did the somber customs of his own people, also. Also, Thulsa Doom's race isn't explicitly corroborated upon; he has dark skin, but also straight hair and blue eyes. Rather than seeming like an African, his race was intended to that of a mysterious, mystical people that had vanished from the world long ago.
