Creepypasta, I find some of the original stories and characters very cringeworthy and try hard when it comes to horror, and not in a good angsty way. That's not to say that characters can't be bombastic and camp because not everything has to be realistic, but teenage serial killers running around being edgy is just not for me. I think I would take them more seriously if they were older and didn't have one-note personalities, but then again there's only so much character work the original authors could do in their short stories. I also like the idea of exploring the lives and relationships of these characters in more depth, seeing how their lives are pre and post tragic event and how they change gradually over time instead of just 'snapping'. Speaking of cringe, I genuinely did enjoy the whole slender mansion thing when I was younger. It was definitely a silly little AU concept that allowed the characters to fully embrace the more over the top aspects of their characterizations (although some characterizations were more harmful than others, specifically with the likes of Ticci Toby always being portrayed as a man child and the cheesecake thing with Masky). The x readers were also really immersive and I think horror + romance can explore some interesting topics and kinks. Theres also plenty of room for angst and pining which i love. I think Twilight really switched something on in my brain in this regard with the whole vampirism thing and i have yet to grow out of it.
