I like to think of Orient as a fast food shounen. It has those things you may want from your shounen: bit of tragedy, some back stories and flashbacks, a couple fights and situations that make characters come out stronger. But in the end, you know damn well it isn't really that good. Can it potentially hit a spot if you’re desperate? sure. But um. Anime isn't fast food. You have options here, so there isn't much of a point to watch this.
But to actually explain what this even is, we have a world where demons exist and are thought of as gods, and the Samurai that fight to protect people from them are shunned. The MC is a miner who's friends with the son of a samurai, the only one in town, and he has a dream of being a samurai himself. There's nothing too special about the premise or it's execution. Sure, I won't pretend everything that happened was obvious, but that doesn't necessarily mean it was good. The world is not particularly interesting either. Everything looks the same, and it's all desert-like and boring which doesn't help. But all that being said, that doesn't mean this is bad. As I said, it does have the basics that you would more or less expect. The issue is that that is all this has. It feels more like the show is trying to hit a checklist of what this should be, rather than actually provide an interesting story.
