That one thing, of course, would be his art. Which is impressive and has shown signs of improvement throughout the years. I know even most of the critics would agree with that, I being among them.
Admittedly, when I was significantly younger, I absolutely adored the comic-the only one really around at the time created by Bleedman. However, my standards were significantly lower, too. Really, the whole appeal to me seemed to basically be the novel idea of inputting some of my childhood fandoms into a story and the amazing art.
As cleverly as he applied some characters from childhood cartoons, and as much as I am for darkening childhood stories for the sake of an interesting plot, he has too many "hiccups", as another reviewer called it, in his plot. These plots are either too random or too predictable in these comics. While there's a few moments somewhat interesting, it's not well put together to have a smooth storyline. Sugar Bits, in particular, is really horrible about this.
Another thing is how he shoves lolicon underwear pictures and the like incessantly, which stops seeming to be for artistic effect when it's in near everything and for not only angles, but brief events. It's awful enough to spam this in a comic(as that's not why I would read such a comic, at all), but he has art that's blatant, lolicon pornography-which, to me, is pretty disgusting. Otherwise, there seems to be at least some subtle and tiny sexism on the author's part in the stories, though I could be wrong about that-somehow.
When it comes to the the matter of the author's personality, I find it worse than his comics-at least possibly so, as I don't know him personally. Which, if I were to be honest, has probably also made me dislike his comics all the more.
After all, he made use of 9/11, in one instance, for his comic-the one based on the Grim Adventures of Billy and Mandy. Note that the use of 9/11 isn't necessarily what infuriates me, but his justification for it-which sounded pompous and was complete bull. Otherwise, the lolicon pornography has somewhat ruined what little respect I might have ever had from him. I don't have some passionate hate against all pornography(and no hate against the use of nudity for art, in the right case), but the obsessive pornography of children? Yeah, I have something against that.
