Short review: great unique art. Definitely one of the better Korean manhwa I've read by far. But I've never liked Korean comics to begin with.

In terms of story: don't expect anything more than guns, gore and seemingly profound but very skippable biblical gibberish interludes. There's alot of intense stuff going on, but at the end I feel like I just read 16 volumes of flashbacks and an introduction to a story that would never actually kick off. And by the time an actual storyline seems to be set up and about to pay off the publication stops. That said, there's no shortage on action. But just alternating between slow, moody gothic tea time breaks and fast-paced guns blazing bloody rage against the devil battles doesn't make for a good story.

I'd say it's worth reading a couple volumes for the art alone, but don't hesitate to let it go if you're not getting much out of it. It managed to hold my curiosity for 16 volumes so it's not all bad, and it's a smooth read, hence the 6/10. If you can manage to shut off your brain while reading, it might even feel deep and emotional.

Conclusion: Berserk + The Crow = Hellsing with cooler art = Priest
Great art, shallow story.
Incomplete!
