The section about Pinkie Pie and how mortals seem to do a much better job of living in the moment might be triggering people's deathist reflexes. Also, Celestia in this story clearly lives a rather lonely existence, not getting to do a lot of the things she wants to. Not exactly the poster child for Fun Theory.
True. Showing immortality to be fun would be the most persuasive approach, but I gave that up early on - just couldn't think of a way to do it within the world of the show and under 10,000 words. Well, more truthfully, I couldn't think of a way to do it that seemed dramatic. Fun isn't dramatic. You could write a series of comedies showing the sisters having fun throughout the ages.
My Little Pony (generation 4) has 2 immortal characters, who get a lot of sympathy from the bronies. "How sad! Poor Celestia and Luna must see everyone they know grow old and die. How much better to die yourself!"
I tried to write a fanfic saying that death was bad. But I had to make it a story, and it ended up having other themes. I don't know whether I like it or not, but it was very popular (now approaching 7000 views in 3 days on fimfiction).
I was pretty sure the message "death is bad" was still in there, because Celestia says things like "Death is bad" and "I'm afraid of dying." So imagine my surprise when comment after comment said, "Yes, immortality is such a curse!"
Why did so many people come away saying that? Tell me what you think. It will help to know that Twilight regularly writes "friendship report" letters to Celestia describing what she has learned about friendship, and that Twilight and Celestia have an especially close relationship.
