I think the issue is mostly about what is art?
Some of the big budget movies feel devoid of creativity and are more a product than a work of art. While I do agree with you that there is some art in those big budget, I think the issue lies in how we communicate a movie.
What is a "good" movie? That's entirely subjective! A better approach would be to explain what you liked (or disliked) about it. Then we can have more productive conversations about it ahah
Sometimes, I think I understand their place too. We're talking about really big budgets here, and while I agree that it's better to take risks so we can get amazing movies, I must imagine the dread the exec that greenlighted taika waititi thor love and thunder to do w/e he wanted.
In the end they let the director loose and still got a mediocre movie. (Maybe it was $$ successful? Somebody know?)
