I'm also confused by this. I actually dislike the antsy "what happens next" feeling, because it's a better-than-even shot that the upcoming twist I can feel coming up is just disappointing and not worth the buildup. I'd much rather just know what's going to happen and appreciate the artistry in invoking the buildup, then how the twist is touched on by every other part of the narrative.

I also try not to spoil anything for people, but I will almost always spoil myself as soon as I get any real interest in what's happening, so I'm not distracted away from appreciating the craft of it. [It also means if, e.g. the character that intrigues me the most dies off early, I can just not participate in it.]

For example: The Only Good Indians by Stephen Graham Jones is a horror novel, which is alright, but the angle of horror it's taking is $familiar_theme + $native_framework. Knowing this makes me more happy to read the book, not less. Otherwise I see some really dumb opinions, like panning The Only Good Indians for having native american-centric conflict in it... when it is very clear in every jacket, blurb, author bio, etc. about the book screams "this is about native american stuff".
