>>50133064You're on the MOUNTAIN of dunning kruger right now. You utterly lack even the most basic understanding of the use of emotion in storytelling. This isn't about disappointment as an emotion in the writing, it's about the emotion you evoke in your AUDIENCE. That's the point of art, the emotions it evokes, the thoughts it makes you have, and the way it enriches your life and how you view things. The most basic simple art appeals to emotion, great warriors conquering challenges, it lacks depth but it has value in the POSITIVE EMOTION it leaves you in the end. Deeper Art, however, can appeal to darker or negative emotions to great effect BECAUSE THEIR THEMATIC MEANING ARE TIED TO IT.
A tragedy like Romeo & Juliet leaves you feeling the despair of the characters, because you're meant to take away something like "wow, needless animosity between families can lead to real damage when reconciliation and love could've easily avoided it" (this is just one interpretation of Romeo and Juliet, do not try to pin me on how I misinterpreted it and it's actually about how foolish young love is). 1984 leaves you shocked and horrified with its ending because it serves the thematic point on how authoritarianism grinds the love and humanity out of us and will leave us lonely and unfulfilled and oppressed. THAT is where unsatisfactory endings gain their true strength.
The Pokemon anime is NOTHING like those stories, there is NO thematic value in Ash losing by the time of XY. The entire show is an incredibly simple story, a great hero conquering challenges, and the ONLY ENDING that can work from a writing perspective at this point is one that provides catharsis for Ash's well earned victory. What value is there in Ash losing again, what did it serve, how did it enrich our lives? It DIDN'T. This isn't about the writer telling us disappointment is the main idea, it's the writer taking a dump on the page and you applauding it because they have the right to do that as an author.
