Captain Planet analogue goes crazy and kills coal workers - Morty is devastated, he agrees it's right to feel bad the planet's dying but the ep implies the correct answer is to do nothing.
Not even 'subversive' Rick and Morty could dare suggest blowing up coal/gas plants without demonising the act (it's quite doable to do such a thing without killing workers....)
Ala a recent trend in modern blockbusters where villains are morally correct in their actions right up until they kills civilians for no reason- just to force a third act showdown, effectively negating their positive ideas.
Also there's an opening joke that is an explicit merch promotion that isn't even ironically done. Just a shitty shirt effectively done to camera. At least Schezuan sauce actually made sense in the show, this was just pure shit. The other eps are good, but the industry in culture industry will rear its head anytime you get big.
i don't actually get what the whole fuss is about WRT the content of the episode itself. I thought it was clear that Morty's issues with Planetina closely mirrored literally every average American's view regarding the climate apocalypse. The only thing left to do is to take drastic action (which Planetina understands). Morty, a classic american lib, doesn't want the bloodshed that would result from taking the planet's health seriously.
