A good story, does some interesting things, suffers from pacing issues in storytelling (especially toward the later chapters). It started out really interesting, with a lot of good plot hooks, and while it does tie everything together nicely, you might be left with a feeling of "wait, that's it?" as the ending seemingly comes out of nowhere. Characters are sympathetic, the art is well drawn (in all of it's gory detail) and I don't feel like it was a waste of time. Just try to keep an open mind and take it at a snail's pace and you will probably enjoy it more.
