Kuzu no Honkai has finished airing and it's been a fun ride, so let's talk about the show.
Kuzu no Honkai is not your tipical romance anime, I've seen many people complaining about it and I understand them (especially after the last two episodes that destroyed my favourite character's personality), as a matter of fact this anime is not suited for everyone: as the title suggest the story revolves around scummy people and their desires, so there's nothing pleasurable to be seen.
Kuzu no Honkai is the story of a girl who discovers her true feelings through sexual growth.
The story's intro is quite interesting: the two main characters try to find solace in each other because they actually love their teachers. After this some supporting characters are introduced and the story takes a twisted and fucked up turn. If you don't care about romantic relationships you'll enjoy the anime until the last episodes, where everything was rushed and hadn't a proper explanation. But I have to say that I really liked how the show ended, I didn't see that coming. Overall it's not bad.
The art is beautiful and I love the animation: the VN like sequences were pretty good and fit the mood of the story.
However I found the character design a bit bland, the male characters looked very much alike, I swear I wouldn't have recognised them apart without checking their hair colour.
This show has one of the best soundtracks among the animes of the winter season; the piano OSTs were soothing and relaxing. Also the voice acting was ok, nothing bothered me about it.
The characters aren't stereotyped and they undergo some development throughout the show (many of them are really worthy "scum" as the title suggests), but I didn't like the sudden and rushed change of some characters, these changes felt unrealistic and forced.
When I watched the first episode I couldn't handle my curiosity and I read the manga. The anime ended before the manga and I liked it, I was never bored when I was watching Kuzu no Honkai even though my expectations were maybe a little too high after reading the manga.
This show deserves a chance, it's not a conventional romance; if you're looking for something original and psychological and you don't care about ships give this show a try. It is very good in its horribility.
