Oh boy, this manga. Is this even a manga? I'm pretty sure it is, but it's pretty different from any other manga I've ever read. Regardless, let's begin.

First off, I should say that I am a weirdo that loves body horror. It doesn't freak me out, but it's something I love to see. If it's a fresh type that I haven't seen before, then it definitely gets bonus points. Say what you will about the plot and characters, but this artist draws horror like none I've seen before. While there's an annoying amount of gore seemingly for its own sake, the truly striking scenes are the facial expressions that the Jinmen can show.

In most Horror manga, you'll have a mildly interesting idea followed by nothing but repeated gore, probably a ton of sexual violence and some one-note, psychological abuse, and probably a sprinkling of "but we were the monster all along" just to earn the painfully average cherry on top. I'm not going to say that Jinmen completely steps over this very dumb tendency, but it certainly approaches things in a different way. In Jinmen, the horror is most appreciable when there's little to no violence, or even any dialogue, and you just find yourself face-to-face with an abomination made by someone who understood the concept of furries from a completely backward view.

To see what was once a cute animal now give you a look of smug contempt as you remember just how low on the food chain we belong can send a chill down your spine. The artist draws these expressions with just enough humanity to emphasize the uncanny factor of the admittedly dumb base idea, making each new expression and animal another look into the horror of their world. This only becomes more unsettling as you gain more and more clues that these animals(?) not only have human faces, but may be gaining a similar level of intellect, as well. With a revelation that only seems clear in retrospect, you suddenly find yourself realizing that you aren't just dealing with animals that do animal things with human faces, but with new creatures that know what they're doing, and seem to enjoy it.

Jinmen is likely a very personal form of horror, reliant of the individual reader's idea of what is scary. As someone that finds the regular old monster interesting, and gore to be aggressively boring, it built expectations of the average story before throwing something that I do fear, and that few stories truly build upon; distrust of the familiar. Distrust of humans (or rather their faces), along with distrust of creatures we arrogantly assume are below us, makes for some scenes to truly chill you.

So, if you're interested what I've described, I'd highly recommend it. If you're interested in an utterly unique setting and art style, I'd highly recommend it. If you're looking for excellent characterization, relatable characters, or plot... eh, it's just as good if not better than most Horror manga.
