John Carter of Mars/YMMV


 * Older Than They Think: Some fans of a little James Cameron film saw the trailer for the Disney adaptation and declared it a rip-off. Unknown to them, not only is this series older, but James Cameron himself has cited it as direct inspiration for his film.
 * Seinfeld Is Unfunny: Probably at the core of a lot of the criticism the film version is receiving.
 * Values Dissonance: So, so much. Burroughs was writing at a time when scientific racialism was in vogue, and it shows; the Red Martians, the most populous (and least advanced technologically) of the humanoid Martians, are said to have originated out of miscegenation between the White, Yellow, and Black Martians, who have been forced into polar enclaves by dysgenic pressure. The fact that the Black Martians are cannibalistic raiders is questionable in modern eyes...
 * Fair for Its Day: ...however, this is clearly subverted because the cannibalistic White Martians are even nastier. Clearly inferior morally to the Red Martians, intellectually to the Black Martians and technologically to the Yellow Martians, the White Martians are easily the most unpleasant of the Barsoomian races. Those hybrid Red Martians (and many of the "monstrous" Green Martians) are good guys and clearly very intelligent, adapting very quickly once not oppressed by the others. The portrayal of women has been compared favorably in some respects to even some modern works. It's even possible that the whole setup was a Take That to the racism of the era.
 * It is also stated that the cross-breeding that resulted in the Red Martians was intentional. An attempt to breed a race that could adapt better to the changing environment.
 * In the first book at least, John Carter is disgusted at the Green Barsoomians for their warlike ways and violent tendencies, but it is taken for granted that his killing of dozens of generally innocent people is perfectly justifiable because he is doing it to rescue his One True Love. The closest he comes to acknowledging that maybe murder isn't the best way to solve all his problems is when he reflects that the guards were Worthy Opponents and fighting men like him. An Alternate Character Interpretation might be that since the story is told in the first person, the reason John is portrayed as chaotic good despite his somewhat chaotic neutral method of interacting with obstacles is because he's actually a narcissistic sociopath who doesn't see anything wrong with sacrificing other people's lives if they get in the way of his personal happiness and that of those he cares about.
