#for the record i don't really care for Chelsea/Ruby ship (especially after that reveal)

[fandoms-and-salt]

The main problem with Ruby gillman movie is that it sends a message that "bigotry is actually justified and your racist grandparents are right". The second, closely related problem is it's villain.

Firstly, if we look at the film without the spoiler-y marketing, Chelsea/Neressa is written as a twist villain. Like Hans Frozen type twist villain, with little foreshadowing and those "sympathetic" scenes that actually don't amount to anything and might just as well be a lie. Even with the marketing, i think the movie still tricked people into thinking that Chelsea might be a misunderstood villain or have a redemption arc or what not. And twist villains could work well, usually if their turn to villainy makes sense with their preestablished goals and personality (eg. Disney's Atlantis). Or a liar villain could work well if the audience knows of their malicious plans, but the heroes stay in the dark (eg. Scar from Lion King). In general, if the twist or reveal makes the story/conflict less interesting and/or didn't have proper foreshadowing, viewers are bound to dislike it.

Secondly, Chelsea is our only mermaid. And she is, well, evil. It would have been better if we had other good mermaid characters, but she is the only one, which, coupled with Gramamah's generous description of mermaids, makes it seem like all mermaids are as evil as she is.

Thirdly, yes, stories for young children about pure good fighting pure evil are generally fine, it teaches them right and wrong, so they can later consume media with more complex lessons. But in those stories the good guys are usually the underdogs fighting an oppressive evil. In mermaid vs kraken conflict, it's actually mermaids who are at a disadvantage. Krakens are big rulers ("protectors") of the ocean with superpowers. The characters themselves admit that Granmamah is a warlord. Mermaids are small, weak and need a magic trident to even match the power of krakens. Their only "advantage" is being popular with humans, while krakens are feared and hated, but humans have no effect on the story or the conflict. If the story was that mermaids are actually more powerful rulers of the ocean, or the kraken family were the just rules but got conquered/overthrown by evil mermaids, or if both species were of equal power ruling their own parts of the ocean and mermaids decided to go and conquer the peaceful kraken kingdom. Then the good vs evil conflict would have looked less like "how dare these evil inferior minorities challenge the rule of our superior race".

Speaking of which. Ruby's first instinct, even after finding out that "mermaids are actually evil" from her granma, is to judge Chelsea as her own person and assume that mermaids can't be actually evil. Which is, you know, a pretty fair and mature response. When she hears that mermaids suffer from terrible conditions, she actively tries to fight what she sees as injustice. But what lesson does she learn? That she should never question her elders, since they do know better. The story is fighting for the status quo to stay the same, while Ruby is punished to trying to change and improve it.

That's all i can say for now. Other complaints i have are:

humans are virtually useless to the story (including the love interest, tho he had some cute moments), they are just damsels-in-distress and trophies for Ruby to save and get approval from. This movie just as well could happen all under the sea with some minor tweaks.

The human designs are weird and uncanny. Otherwise the visuals are fine.

Ruby's arc is kind of all over the place with her main arc being the classic "believe in yourself", which she mainly gains through hanging out with Chelsea. But isn't Chelsea supposed to be the villain who "leads Ruby astray" from being a good citizen who is not skipping school, lying to her mom or ignoring her friends and crush? Make it make sense, movie.
