I read the novel first, and I absolutely adored it. It was dark and it is like what that ANN reviewer said. Its not as focused on being a full out comedy more like what the anime tried to be, Thats why I felt the conclusion a lot more shocking and in place than what it was in the anime. I haven't read the manga, I want to get a hold of it when I can though. I read the novel without any preconceptions or anything and I just loved it. Some of the extremes of what that ANN reviewer said was a bit off, I found the translations great as well.
This has got to be like the only novel I've read all the way though, And its not even a -light- one.
People who know things; How different is the manga to the anime and the manga to the novel? Thanks.
