In watching the excellent sci-fi thinkpiece, I was reminded of some Jin Yong parallels, and I thought I'd just share those thoughts
***SPOILERS***
In particular, the way that everyone in the movie wanted the arm, evokes how many individuals in Smiling Proud Wanderer wanted the Sunflower Manuscript. Both the arm and the manuscript were actually damaging to the body (I consider eating alien arm and/or undergoing inter-species mutation to be damaging), yet the power-hungry people lusted all over for it, as if it was the best thing since fried chicken.
The "interracial" Wikas also evoked Xiao Feng from Demi Gods Semi Devils. Both were torn over their new-found race. The difference is that while Xiao Feng was neutral and did not favor a side, Wikas seems to have chosen to become an enemy of his original race (not much of a choice for him, but he was definitely more aggressive to his original race than Xiao Feng).
Any other parallels you see?
