Violence: There is some violence and death, though this is minimal. I can only think of one death scene that can even be considered bloody. There is also an attempted suicide and references to death. There are also frightening images, which is the reason I stacked things up to a four.

Sex and Nudity: There's nothing even remotely sexual about this show, since our main cast is a bunch of little kids. There are two scenes which feature the little boys in the shower. Everything is censored by steam, and it's very innocent in nature.

Theological Themes: Spoiler: There are monsters referred to as demons, though they aren't actually demons, more like a species of magical animals. There are also references to a couple of demon religions, including one, where a prominent demon character is worshipped. The content about religion is minimal and only in the second season.

Problematic Themes: There is some light, mild swearing during stressful times. Nothing worse than the d-word is ever uttered.

Overall: The first season is glorious. The atmosphere is creepy and tense, and you find yourself frequently at the edge of your seat. It's full of puzzles and mystery. I'd say it's fair to classify it as a thriller. It's definitely psychological. Everything is meticulously plotted, and the characters are great. Emma, Ray, and Norman all have their own ideals and plans, which sometimes clash, adding extra tension. They're all well developed and believable characters in their own right. The villains are downright unsettling. The opening theme is one of my favorites ever, and both it and the ending theme are actually pretty creepy once you've seen the first episode. The opening is actually even weirder once you see the whole thing and hear the English lyrics. If this were on its own I'd give it a 10. Unfortunately, its' not.

Season two started off okay. I liked the first few episodes. It shifted gears to a more action, adventure-y type story, so it was different than the first. The opening was creepy, though more creepy imagery than "random stuff that looks normal but isn't really". The ending theme was really nice. I liked it. However, most of the creepy vibe vanished. Scenes that were supposed to be creepy were undermined. I was particularly frustrated with how the characters were treated. Emma was the only one who's actions really held any weight, not to mention she was kind of a Mary Sue this season. I'm not even going to start on how horribly Ray was treated. I kind of lost patience towards the end, as everyone's motivations and ideals start changing without any foreshadowing or second thought. I didn't think it was as terrible as people say, though I haven't read the manga and can't talk about cuts or anything. I gave it a four, and the overall score averaged out to a seven, so a seven it is. I recommend this series to teenagers and up. Definitely watch the first season. Fans will likely be disappointed by the second.
