I personally love this anime! After reading the manga I think it was a really good and interesting concept. Almost every single character had a sad and heartfelt story that makes you feel sympathy.
Anime wise, animation is god tier. It's amazingly stunning!
My only problem is the writing, if I'm being honest I think it was kind of predictable. Each time they would defeat the demon without fail, it was kind of like the protagonist (Tanjiro) couldn't die because his family just pops up.
Other than that I recommend watching this anime if you are a beginner anime watcher ✨
