Just a bit of Gerry Canavan on Avatar and the question of genre, re science fiction
In the beginning Avatar seems to situate itself firmly within this generic mode, with a group of scientists and mercenaries from Earth who have arrived on Pandora in spaceships to study the natives and drill for valuable minerals (not necessarily in that order). But by the end, while Avatar certainly remains an alternative to our empirical environment, it no longer operates as any kind of framework. Neither the biological/ecological systems present on the planet Pandora, nor the ability of our biological structures and technological apparatuses to interface with them, are remotely plausible from the perspective of either evolutionary biology or cognitive science without inventing some sort of massive hidden backstory for the Naâ€™vi that involves incredible prehistoric genetic engineering on the planetary scaleâ€”and really not even then. (And of course Fridge Logic just makes it worse.)
In Suvinian/Freedmanian terms, then, Avatar isnâ€™t really science fiction at all, because the type of imagination involved in its reception isnâ€™t cognition. And by the end of the film any pretense of scientific plausibility or internal logical coherence has been abandoned altogether: telepathy and transmigration of souls are real, MechWarriors pull Bowie knives from their belts, and not even gravity seems to work anymore.
The overall critique here makes sense. As I watched the film I never considered the genre really as science fiction but as straight forward “fantasy” as magic or “faith” is the core logic of the narrative.
