I thought the Castellano dub was the melodramatic one, in the first memory zelda sounded like she was overacting, especially with that gasp of air she took, sounded like she was dying. The LA dub was less dramatic than that one. Though i haven't seen the other scenes yet in the catellano dub.
The La spanish Dialogue is definitely better written than the english one. When Zelda was talking to the deku tree in La spanish the tree says,
"The most important words, those that come from the heart, are said in person. Don't you think?"
In english he says, "words intended for him would sound much better in the tones of your voice. Don't you think?
I did see the Spain spanish for this scene, he says,"If your message is so important, should you not be the one to transmit it?
The La spanish was best written, much better and more personal, made it something zelda really cares about. I thought the english dialog was next best as it conveys that its better said in person, using your own voice to express how you feel. The spain one was just, you have an important message, shouldn't you deliver instead? It doesn't express that its something that comes from zelda's heart, that she truly cares about it like the other dubs.
In he same scene I also liked in the la dub how zelda delivered, "y esta vez no fallare." Better than in spain dub. The la spanish was more emotive over all but not over done in the memories than in English, I thought. Also when zelda was talking to the king she sounded nervous in the la dub when he first came out, she didn't sound like that in english. And the king sounded like he cares about zelda in la spanish acting, especially when he says, entendido? Then he expresses when he's mad at the right time when she came out with excuses. Compared to english where he just sounds like he's just plain mad.
He also says in la spanish, "Do you know what they say about you princess? People see you as immature, irresponsible, and incapable. Prove them wrong understand." He sounded like he cares for zelda and wants her to succeed.
In english he says, "They whisper amongst themselves, That you are the heir to the throne of nothing, nothing but failure. It is woven into your destiny to prove them wrong. Do you understand? His delivery didn't sound like he cared about zelda that much, and that he was just commanding her to do what he says because I say so. Over all, It was just better in spanish than in english, in acting and in writing.
