And where did you get "you won't see this so I'm going to entirely disagree" from?
But I feel like it would just keep going in circles and end up with you not seeing how your average mermaid who lives under the sea could be black. So I'm just going to end with I fully disagree with you.
Then why is this an issue for you at all? And why did you go to such lengths explaining it?
Because there's more than just the basic "correctness" of things, and you can add layers to it.
Just because something kinda works doesn't mean I can't think of and say some changes or ways to (in my opinion, of course) improve it, or why something wasn't as precise as it could've been.
Like I don't leave KH III alone just because it works on a tecnical level and provides a story of a good guy defeating an antagonist.
That's there and it works on a basic level, but it doesn't mean we can't go in detail and see if everything works or could've been made differently.
About going to such lenghts, that's the tricky part with side issues. They're not immediate to many, so you have to go on tangents sometimes.
Which often leads to you looking like a nitpicky dude who builds crazy theories just to dislike something, that's why I stress it: this isn't something that destroys the movie. It's simply why I think a black mermaid doesn't quite work.
If I'm not the first one to acknowledge it's not that big of a deal, then I definitely would be racist or a pathetic person for putting such emphasis on this.
On that note go ahead and get some sleep, friend. You've explained yourself and I understand where you're coming from and you skepticism. It's all good.
EDIT: okay I messed everything up with the quote layout, I'm sorry.
