+pretty cool fight scenes
+nice aesthetic that reminds me of mass effect
+interesting, tho surface level exploration of ideas like ai, human replacement and dystopia

-the antagonist behavior was nonsense. after he learned he's a robot, he had no motivation to fight the mc: in fact, he should have joined forces with them
-the ending was nonesense too. supposedly the planet is ruined by suddenly there are forests everywhere? and were is the robot supposed to go alone for spare parts?
-thematically, first the movie makes a point that robots are not the same beings as the humans whose brain was transferred. yet seo hyun goes out of her way to give robot "a chance to live for herself", what's the point, that's not her mother, her mother is in coma.
-several characters behave in erratic and idiotic way, makes you wonder if everyone except the mc is replaced by synthetics already. perhaps that was intentional, but it didn't make it any less annoying to watch.
