TaoPaiPai said it well. I have to give it some points for starting okay, but after that everything really just goes down hill, fast. I am very confused by people giving this 10s, and saying the art is great... what? What is great about the art? Is it because you can usually tell that a person is being drawn, simply because sometimes you can make the arms and legs out? Is that what makes this art something wonderful?
One more thing, for people who think it is really -just- the art that makes people label this as crap: You had to read far into it, and possibly several times.. a little bit of understanding of the human mind would explain why this crap starts looking good. It is the same reason that listening to a really really horribly offensive, in all ways, song it will start to sound good if you listen to it often enough. Something like 10 times and the song will start to sound good.
The same with really bad smells, if you are stuck in them your body will adjust so you don't smell it anymore, or so it doesn't smell bad to you. Hence, this is crap. You forced yourself to trudge through this crap more than a normal person would. You were rewarded by your mind adjusting to the crap in such a way that the art might seem good to you now, or the convulted story might make as much sense as a twisted picture. Good job masochists. ^_^ This is for people slamming the negative reviews, thinking that people who don't like this series assume we are brain dead bafoons who only saw the cover and never attempted to actually read this stupid thing.
Look at the guy down a few posts who mistook a panda for a skull, but still gave a 10. Come on!
Anyways, besides the absolutely horrible art, and the fact that all the characters have the same look on their face of "Hrm, well, today happened... yup" and the art making it so you can't really tell to many characters apart, add in the fact that so many characters are introduced that look the same, and it becomes one big mess of characters and talk. Eventually it breaks down to just looking at the pictures and trying to make up a story to go along with it, because the story itself is so inane.
So yeah, art = bad. Story = confused and annoying. Characters = Characters, where? Overall = Find something else to occupy your time. After the first little bit of "this could be interesting" it swiftly turns into a giant mess that makes the Gordian Knot look like child's play.
