There is no reason that I know for why Aquaman turned into the modern CGI version of The Little Mermaid, liberally mixed with Aladdin and The Lion King. I mean, yeah, Black Panther was mostly Lion King, but it was interesting and fun and the world building was not bad. Aquaman feels cartoonish from the start to the very end. The pointless CGI, Heard's horrible wig, all the fairy tale characters that seek to show us how they are superior to people on the surface who have grown up reading about single dimensional characters like them, the predictability that one can find in children stories only. To be honest, the feeling I have most about this film is outrage. It is condescending and dumb. It's the Hollywood version of Homer telling Bart he's stupid.
And then there is the cast. Jason Momoa, who I liked in Atlantis, the Stargate one, because he was supposed to have only one dimension. Amber Heard, who hasn't had a good role in ages and sporting that eye soar of a bad wig, Nicole Kidman and Willem Dafoe getting their paychecks. And Dolph Ludgren? WTF? The main character of this story was Patrick Wilson's, he had the most relevant scenes, he was the only one who actually looked like he gave a damn about his performance. He is the true king of the film!
Bottom line, it was so dumb it was offensive.
