I'm talking in general representation. Most people, including the Japanese reviewers who are getting the full story, are more upset with how Yuna went about reviving him rather than the fact that he's back.
Sure, him dieing two days after he just came back is a shame.
But hearing how he came back is much more shocking and apparently upsetting than the simple fact he was revived just to be killed again.
It's a novella either way.
They're taken with a grain of salt usually.
Only used for their overarching plot points.
