Unfortunately, the majority of the viewers know as much about psychology that everyone should know. The show brings up movies, music, TV, games, but not to blame them for the killers' actions. Everyone is affected differently by different things. If you have prolonged anger and depression in your life, and you start listening to death metal and watching horror movies, THEN you may well wind up being a killer. Everyone starts out with different mental strengths and weaknesses. Whoever starts out with just the right weaknesses, you had better hope that they don't get drawn to watching or listening to these things that it may sound like this show blames. That does include the occult, Ouija boards, witchcraft and the like. It's not uncommon for people who get into those things to end up killing at least one person, as research can show you.
And as far as the narration goes, the IMDB cast list shows who has narrated. They are not little girls. I wouldn't want any little daughter or niece of mine narrating a show like this. Some adult women can imitate a child's voice very well. Some have a natural little girl sounding voice. A famous example (especially for horror fans) is the late actress Zelda Rubenstein, famous for playing Tangina, the spiritualist in the 1980's Poltergeist movie franchise. Of course, she was a "little person"- many of them have higher voices as adults. But guess what: her voiced added a little creepiness to the movies, and the narrator voice of this show. I thought of Miss Rubenstein right away when I first heard this narration, but she died the year before this show started.
So you might choose to think the narrator voice is inappropriate because it sounds like a little girl, but it's not one. You may choose to is like the choice of voice sound, but I can see both how some viewers can find it tacky while some others may find it creepy and either dislike it or welcome it for that reason. Not having seen many episodes yet, It has kind of grown on me and you may need to let it grow on you. You may also view it as weird, but you might be welcoming of weirdness.. I like weirdness. Bring it on!
And this show is pretty good too. I'd recommend checking it out with the thing I said in mind.
