Again if I don’t phrase things properly don’t think I’m taking you out of context.The animated movie was always about more than leaving the ocean for a boy. But the shortcuts made in plot made it easy for people to dismiss it as that. The additions to the live action make it harder for people to write off in that manner.
I find the additions and accompanying explanations of motivations to leave the ocean beyond the boy, make the plot convoluted and longer than necessary.
I don’t see a problem with her just leaving the ocean for a boy.
Maybe you do and that’s certainly fair.
