A really unique and bizarre masterpiece Dorohedoro is the kind of anime that you wont experience a second time anywhere just like JoJo's Bizarre Adventure, the story and Worldbuilding are extremly creative (probably one of the most creative ones i ever saw). Its an extremely beautiful anime with one of the best shots in the medium, the voice actor also did an amazing job, the cgi was also pretty nice and it works pretty good in my opinion (if you didnt like the cgi but still love the concept just read the manga)
So if you are a fan of really bizarre but also new concepts of art, Dorohedoro is the perfect anime for you, but i would still recommend the manga just bc its art is even more breathtaking
