I picked other on reading a deathfic and "never, I love the characters too much to kill them" for the writing a deathfic. For me, the issue of reading a deathfic doesn't have to do with whether it's exceptionally well-written or not. I liked When Magnolias Bloom because L&C were together throughout the entire thing. I don't really want to read about one of them being left without the other, so a readable deathfic only works for me if L&C aren't really separated.
That said, I realized almost as soon as I voted that I may have cast my vote on the second question incorrectly. At the time that Nan was writing her original "Home" vignette, I was tossing around the idea of writing a novel-length story (100,000 words or so) that surveyed L&C's life together if Brutal Youth didn't really take care of Clark's extended lifetime. I planned to follow them through important moments in their lives and end with Lois dying after a long life together and Clark waiting for her return. So, while I haven't written a deathfic and won't do so now, I did plan to do so at one time.
BTW, Wendy, regarding your comment on the other poll about why I felt it necessary to check the ending in a story in this fandom: since my son's death, I have little tolerance for reading about the agony that follows the loss of a loved one. For me now, there is nothing cathartic about reading about that kind of loss, so I needed to know that the character survived, that it was only a brief separation.
