>>2544881Im gonna talk about shonen and harem because seinen is fine as it is and shoujo is for girls and fags.
Start by making the MCs decent, give them a genuine reason to do the shit that they do. I dont mean to make them alpha bulls, but to make them complex and interesting enough not to be just a blank slate viewer insert relatable beta virgin.
By giving the MC some redeemable qualities, the girls wanting to ride his dick starts to make sense. And talking about the girls, that -dere trend needs to die, we want interesting and charismatic characters, not walking tropes with cute/sexy designs for selling merchandise. If a character can be defined accurately in just a word, then that character, who's probably someone's waifu, is shit. And talking about shit, the writing needs to get better, everyone's fucking tired of seeing characters being dumb and getting into arguments because they cant explain basic shit to each other. Dialogue tends to suck a lot of dick, no more useless exposition about how magic works or things the viewer could figure out by themselves. Villains need some work too, specially their power relation to the MC. I'm fucking tired of seeing deus ex machina asspulls with no foreshadowing used in the climax of an arc because the writer thought that having a bad guy 10 times more powerful than the MC was a good idea but couldnt make the MC numbers bigger without retconing something.
If you really wanna see everything wrong with your average anime, watch RWBY, it gets everything wrong about what makes a show interesting and I'm going to watch Volume 5 just for the cringe factor.
