Eh, I think this one could have plausibly ended with something like "And so I remain out here in the cold, forever one of the NIMBLE MEN" with the last words in that like wiggly-outline font from old horror comics. Either way, if I based my enjoyment of stories on whether I was surprised by the ending, I'd never have any fun. I gave this one about a 3/4 chance of ending with the main character alive, but I haven't actually been shocked by a plot twist for like a decade now. As far as I'm concerned, an inability to guess the ending ahead of time usually just means the story was badly written and has some kind of deus-ex-machina left-field denouement.
Me, I'm more upset that the homoerotic tension was left totally unresolved. There's a reason he's not going for the stewardess, people! C'mon now, I couldn't have been the only one to think that, huh?
