Noblesse

The original webtoon is all right, but it has a lot of flat passages, especially at the start. Luckily the anime moves fairly fast through those less interesting passages, unfortunately it does not make them exciting either. Part of the problem is the flatness of characters, basically only intriguing character is Frankenstein and rest is just a generator or extra combat scenes.

Do not expect it to be more than an eye candy battles and endure the flat story progression, it gets better the further the story goes.
