No. He’s not missing the point. He’s saying the point is stupid.
Open your eyes. Problematic origins exist for nearly every piece of entertainment we consume. Super Mario is an Italian stereotype. Someone brought up Indiana Jones’ racial depictions. Mickey and several other cartoon characters have done blackface and fought “cannibals”. Pokémon had Jynx in the original 151. But we let these slide because the companies did what they could to fix them, and the majority like these IPs.
With Splash, it’s deemed okay because nobody really cares about SotS. Barely anyone’s watched it, and if they have, their opinion on it was made up long before they pressed play.
It’s easy to hate on something you don’t care about. It makes you feel good because your “in the right” without making a huge effort to do anything morally just. Flip the tables. Something you love is called out, perhaps unfairly, and you’ll be defending it like we are.
Splash did just about everything it could to give an interpretation of the stories that wouldn’t offend people. It was an easy target for people to get their moral jerk offs.
