Harlan Ellison. The only way the series can be redeemed is if all the characters are tormented to the brink of despair while I get to watch.
Serious answer: KJ Parker. Massive history and lowtech sperg, can torment characters and fuck fans over like no one else, still alive.Just the cheapest hack they can find. I’ve always liked the idea of ending an epic fantasy series with a final volume that’s just a total “fuck you” to the fans. Something like they’re about to get to the climax of the series and then Jon Snow wakes up and it was all a dream.
...ok now im yearning to see a CS Goto penned finale to ASOIAF in which Jon Snow's sword randomly transforms into a laser minigun, Stannis Backflips himself and his horse during the battle with Ramsay Bolton, and the White Walkers get largely wiped out by northerner children throwing sticks and rocks at them.One of my picks was Aaron Dembsky-Bowden, or basically any of Black Library's decent-ish writers (Sandy Mitchell finishing ASoIaF would be worth it just for the lulz; the grimderp suddenly transforming into self-effacing Flashman-esque narration would cause REEEEEEE sign the likes of which God himself has not seen.) The only real criteria are 1) writing assholes in such a way that the audience wants to keep reading and 2) actually finishing the fucking work on time.
