Pet Peeves in Shounen?

Everyone keep asking about pet peeves about romance nd that shit, but lets switch a bit. What's your pet peeves in shounen? For me, its when the author kills off almost every character nd calls it "good storywriting". It's dogshit, never do that bs. It's just annoying, unoriginal and not fun to read/watch when all of your favourite characters dies. Nd when the chapters (talking about manga/manhua/manhwa here not anime) used to be long but suddenly becomes shorter in each new chapter, also the plot becomes confusing. It's so obvious that the author doesn't want to continue the manhwa/manga/manhua anymore. Jst drop it atp. Nd also when the mc is so overpowered its unbearable to read/watch. Like what's the point of reading when the most basic average looking guy that gets all of the bitches and also don't forget black hair just killed the strongest being in the whole universe? Wdym he killed the creator of space? get that SHIT out of here. I have more, but bro ion got time write allat.
