Why do you suppose it is that kids who are into anime tend to have an almost exclusive interest in dark, violent, and morbid types of anime and manga?

Growing up (6th grade to senior year) I liked comedy in my anime and drama in my manga (mainly because drama meant beautiful art).

They're impressionable. They're young so chances are that they haven't seen anything with actual plot or detail that speaks to them (or they don't have the life experience to enjoy/appreciate more emotional stories than action stories). So they see a character gain abilities out of nowhere and kill a dozen people, then they go "Wow!! Cool!! He did all that!"

Lol, I remember loving things like Ninja Scroll, Berserk, Samurai X, ect when I was young / in my early teens. I don't know, I guess it just seemed really cool watching violent things, the same reason I loved violent video games. Like, it was so cool to own and play the GTA games maaan, "Cause my mom let me get it I'm so cool!". I mean I liked good stories and diversified my genres even then, but nowadays I seem to definitely appreciate a good story more than I used to. I think it's just pretty normal for kids to be curious about things that are like, taboo and stuff. v(´-ι_-｀)v
