In response to damoose's post about stories where zombies win can be good if the story is well-written, I agree. But I also agree naeblis in that Fidele did not lead into the ending that we got.
Barahir said that the reader was supposed to feel some sense of optimism about Luke at the end, but in my reading he seemed like he was falling into despondency about missed opportunities with Kathryn. He had strong feelings for Rose but seemed to have no idea how to envision a future for them together.
Kathryn's story cannot be considered anything but depressing. After Luke moves out she is heartbroken when he flees the country, ends up in an irreparably damaged marriage with her husband, who dies within a few years. She has it out with Luke after the funeral, ends up drifting for about a decade and dies early from cancer, with only a distant cousin there with her. It's implied that she has more sexual adventures with Alejandro and Faith, but it's pretty clear that her life post Luke was unhappy and without much in the way of love.
Luke, as discussed, seems quite damaged. I thought that the epilogue was leading towards him ending up with Rose, but that wasn't even an ending that I wanted after learning what had happened to Kathryn. Luke and Kathryn were equal partners in their affair, and given how shitty Kathryn's life was after Luke left, it wouldn't have seemed right for Luke to essentially get a do-over with a woman who has nearly all of Kathryn's positive qualities, and none of her baggage (childhood sexual assault, inability to bear children). It certainly didn't feel like Luke "earned" a good ending, because in his misery he was objectively terrible to people who cared about him (Kathryn, Wendy, Irina, Faith, Olivia, etc). In my view, Luke is a much less likeable character by the epilogue.
Bill is a flawed yet sympathetic individual; he dies early and it's clear that the marriage didn't go the way that he hoped. We don't hear anything from Wendy after Luke runs away from her after the funeral, but it seems like the once-strong friendship between Luke and Wendy is gone. And Wendy didn't end up with Irina, whereas in Luke's dream we were led to hope there would be a future there.
And as I mentioned previously, I just didn't like the idea of Luke and Kathryn not attempting any sort of reconciliation after Bill's death. Their love and attraction and sexual chemistry was such that they almost ended up in bed the night that they met, Kathryn engineered a way for them to spend more time together, and within a week and a half they were engaged in a torrid affair where they quickly and easily expressed their love for each other, explored together sexually, and people like Faith and Irina believed they were meant to be together. It just doesn't sit well for me that, after Luke left the guest house, they have one face to face meeting in a hotel, shortly after Bill's death. It doesn't feel like a love as powerful as the one we saw in the first 40 chapters would be left to languish by two people who are essentially miserable without each other, and who (especially after Bill's death) have no reason not to attempt a relationship.
I was prepared for an ending where Luke and Kathryn end up happily together, or one where they are deeply in love but her sexual adventurousness ends up causing a rift. I was also prepared for her to stay with Bill. Or for an ending where she leaves Bill, but either due to the manner in which she took up with Luke or because their relationship is too explosive, she doesn't end up with Luke and ends up with another Bill-like character (an older man who can give her safety and stability, but for whom she doesn't feel the same depth of passion as Luke). And maybe Luke ends up with someone like dream Olivia who is extremely loving and caring towards him, but not as adventurous sexually as he might be - or he ends up with someone like Liz who is quite adventurous, but less loving. Essentially, Luke and Kathryn end up "okay" but lacking the powerful love, romance, sex and overall chemistry that they shared. The ending, to me, took a bunch of generally Overall, the ending that was written took a bunch of likeable and sympathetic characters, and shit on them for reasons which I can't understand.
And one thing I want to make clear, while I did not enjoy the last couple of chapters, overall I thought the series was outstanding, the best story I've read in some time. The characters were very nuanced and I discovered new layers to them as I went along. I normally just read a story and move on; this is really the first story that I've engaged with the author and other readers. I don't want my critiques of the end to overshadow just how much this story connected with me.
