This was a disgusting ride, and if I had to rate it as a horror or a mystery or tragedy genre, it'd be somewhere areound a 7/10. But it mixed those things together, gave us a good, "real" perspective on a miserable person's life, with "real" thoughts and reactions and going trough his head. The usual tropes are here, the story itself is retty damn by-the-book... but it's executed very well. I won't complain about cliches for this one, because those cliches were good. They were the results of good storytelling, not the result of being thrown in there simply to appease the masses.
There's a simple story here, a dark one that pretty much sucks for all the characters in it, but that story was written very well, and the artwork was perfectly suited to it . Those goofy, unrealistic monster-smiles on the cover are the only humor you'll find in here (besides some dark, twisted irony), and they don't even come across as intentionaly humorous once you get into things.
In the end, I'm giving this a 10/10 because it was so well done and kept itself together the whole time. There was no pointless filler to stretch it out, nor was anything important missing or left unresolved.
