I think seeing the death isn't the problem. I think the accidental nature, the randomness of it as an event, is unsettling from a pop culture point of view. The Kirk of legend should have a legendary death.I mentioned that Kor had a better exit, and realize that what makes it impactful is that we don’t see his actual death happen. It’s left to our imaginations how he was able to accomplish his mission and sacrifice himself, and that makes it more powerful.
I dunno if that would work for a MOVIE, it definitely needed to feel grand in a sense. A more mythical type of death you hear told in stories.
I don't know how it would look necessarily. I think Kirk defeating Soren by cleaver means would be more satisfying and making that sacrifice by trapping Soren in some way.
