As expected of KyoAni, this show is worth watching for the production values alone (which makes me all the more sad KyoAni refused to animate Little Busters). I also found it funny they cast Clannad's Tomoya and Sunohara's VAs for the main roles in this show as well. The dudes aren't even that much different from Clannad, aside from Fukube obviously being a capable fellow, as opposed to the ever-loser Sunohara. What comes to the story, though... Hard to say if it floats at all.

The MAL description in the OP contains some errors. Based on the novel description on Manga-Updates, I don't think it's even a difference derived from there. It must be written by somebody who knew nothing of the story... Or, rather, knew something of it, including spoilers, but didn't have the wits to write a correct or proper description.
