The "DEAD" in the title says a lot about this manga.

Gore is an extremely important element of this manga, so if that's not your thing, don't bother. Otherwise it's a great manga, though the latest arc had a lot of people confused and/or disappointed.

The art style is pleasant to the eyes. Some characters look a bit similar though, which is pretty much the case for most manga.

I personally like this manga because of the pretty and unique characters, the unexpected events and, to a lesser extend, the gore.

Conclusion: this manga is totally worth your time, unless you hate gore.
