The entire story is very drawn out to such a degree that you'll probably get bored of reading, it's clear the author probably didn't want to continue with the series but was forced to due to some outside force like the publishing department or something and it really does show after Season 3 but it shows it's head throughout the other seasons.
When reading I felt as if the characters were literal sponges, they don't think throughout the entire series, which if they did then they would have prevent this entire mess, most of these characters then try to get all the pity when their actions have consequences, even in situations where character's shouldn't act like this they just do.
I don't mind the art, though the fact that there's not much shading seems a little weird.
I think if you want a series which is arguably more interesting, is set in a school, there's drama, is a similar length, etc, then try reading Unreachable Girl.
