1)you don't have to relate to the hero, relatable one form of story telling, ideal heroes are different form, they ones strive to be not the ones relate to, you don't relate to superman or wonder woman but their ideals you can strive for, what tlj did was say for most of the movie you shouldn't be like luke you shouldn't be that ideal, because you will just wind up a bitter old man, who ran away, whose action didn't make the world and he didn't, that strive be that ideal you will just bitter alone and everything you tried will mean nothing that's the take away i got from tlj did until the final climax when it's too little too late
2)luke is a legend a legend that inspired millions of people, tlj spent a good bit of that plot being "you shouldn't meet your heroes" and "you should strive for those heroic ideals", and if like you said the movie realizes luke wrong at the end and you were take away from, then WHY IS LUKE TELLING REY HE WAS WRONG TO RUN AWAY AND ACT LIKE HE DID ON ACTO IN THAT SCENE IN TROS A HATED PLOTPOINT
3)Not every story follows giuidelines, some don't and are very good stories , some do and are bad, there is no write a story, but there is definitely a wrong way to do things, taking a person who an inspriration for some many, people and turning into a person that you no longer want to be is wrong, i don't want to be the luke in tlj, the one biiter the one who hates his life, the one who believed he was wrong to try to make the world a better place, the one who was bitter alone and died alone, not surrounded by his friends, not surrounded by his family, not in a better galaxy that he made better. I stopped wanting to strive for ideal luke set.
he's relatable sure but he is no longer someone i want to strive for that is something LUKE SHOULD NEVER BE
1)Luke never was an ideal hero. He was a character on a heroes journey arc (which arguably is continued in TLJ). He was a substitute for the audience even in ANH, an easy character to project yourself on. But even when you want to present Luke post-ROTJ as this perfect hero on a flat arc, that would not serve the actual story of the trilogy up untill then very well. A flat arc is a hero with a certain ideal or world view, who gets that ideal tested heavily through conflict, but never wavering, to in the end confirm that ideal by changing the world and characters around them.
But Luke isn't the only protagonist here. He's not even the main one. A flat-arc Luke would not serve Rey's story nor her character. Because Rey is not the person to doubt his ideal, let alone make him doubt. She would only confirm, and not test him. That's who she is. When Rey goes up to Ach-to at the end of TFA, she's there to bring Luke back and hand over duties to him, with the hope he can be the one who shows her the way. That's what she wants. You can't tell a story if you give your protagonist what she wants in the first scene. The story is over, nothing is learned, nothing is told. You need Luke to be reluctant in that moment. You need Luke to make her doubt. The beauty of TLJ is that it takes this set-up to build both characters.
And we as an audience are close to Rey in how we look at Luke, and we're taken aback too. That's why it's so gratifying when he does come around. It's cathartic.
2) Again, that is NOT what TLJ tells us. A stories message is AT THE END. A story can make you doubt yes, can throw you of and make you reflect. So yes, we doubt. Maybe Luke is right? Maybe he isn't the hero we believe him to be. But at the end he's confirmed as that inspirational hero. One who has overcome an extra, very personal set-back (And this is someone we should look up to, because he pulls himself up at his bootstraps, like we all have to do sometimes). It's LITERALLY HOW A STORY WORKS. With your argumentation here, you could also say that The Lion King tells us the whole second act that it's good to run away from your responsibilities and live with no care in the world, to leave the past behind and never look back, because only at the end this is reverted when Simba comes to his realisation you can't leave the past behind, but that you can learn from it. Don't you see how crazy it is to look at a story that way? To deny what it tells us as a conclusion at the end, because it explored other viewpoints first (to show us those are wrong)
And why do you underline and place in fat and all caps something I NEVER SAID? I don't take issue with that scene in TROS at all. Those who do haven't understood what TLJ tells us.
3) Most stories do follow certain guidlines or fit in certain story types. Those aren't a recipe for succes, true, but they are a way to both structure and build a story, as something to analyse them by.
There is literally nothing wrong with telling a story about a hero struggling with his legacy because of a mistake he made, and then have him trough conflict with someone who looks up to him see the error of his ways and ultimately step into his role as hero and inspiration. That's a story as good as any other, as worth exploring as every other. Literally nothing is inherently bad at that idea. It might be something you don't relate to, or something you didn't want. But that doesn't make it a bad story. It just makes it a story you personally don't gel with.
What it is above all is a story that tries to push a series forward, offer new perspectives and explores new themes. Even more, it's actually a story. That's not something you can say from Luke's cameo in the Mandalorian. That's not even a real story on the level of the scene, and it sucks all attention away from the actual story at hand. Takes the agency away from the real protagonists (in the season finale too!). That's what people take issue with. It's basically a slight of hand magic trick to elicit a respons from you as an audience, in stead of having an emotional response to an actual story. (It's somewhat saved by the touching Grogu goodbye, but that doesn't change a thing about the fact the conflict is basically resolved with a deus ex machina that's hidden behind the excitement of seeing Luke.)
In the end I liked seeing Luke in that moment. But boy do I wish it didn't choke the actual story that much, and didn't create such a disconnect between my own emotional respnse and the one of the actual protagonist. Because ultimately, it's a completely hollow moment, that only thrives on callback and nostalgia, and not on the power of story. And that's a damn shame.
