I am reading the last book in the series
I recently watched both
John Carter & an earlier 21st century version of the story titled
A Princess of Mars. The Disney version JC, was a joke! Everything that made Carter what he was, was changed.
Carter was a man who loved to fight, was the best swordsman on two worlds, & yet, Disney's
John Carter made him a pacifist, who was unfamiliar with a sword. Dejah Thoris was the one who saved him, & she was both a warrior & her nation's best scientist. I know the ERB's stories were anything but PC, but this thing just went too far. [Pukes]! There are just too many plot elements that are backward, upside down, inside-out, or fun house mirror reflections of what they should have been.
On the other hand,
A Princess of Mars, was fairly accurate to the novel of the same name. Its fault was also the Disney version's only redeeming feature.
A Princess of Mars had modest special effects, & most of the creatures / beings were physically very different from ERB's descriptions of them. the Disney version, while having accurate physical representations of beings & creatures, offered nothing else worthwhile. If only they had used the screen play of A Princess of Mars when they made
John Carter! I had though that the film's failure was because of a poor advertising campaign; few people had any idea of who JC even was. But I was very wrong.
Anyway, I am now reading the last story
SKELETON MEN OF JUPITER, & I can safely state that none of these stories would make it in our age, they are pure chauvinism; all the women are abducted, or fall into enemy hands & need the big strong heroes (not always John Carter) to save them.
There are some elements that may have inspired other SF tales. In SYNTHETIC MEN OF MARS, there is an ever-growing blob-like (for lack of a better description) creature that may have inspired THE BLOB.
