as the rating says... Outstanding (6x times in a row).
Outstanding Script,
the series had; Exellent voiceacting on a 1st-class-level (couldn't have had a better cast).
exceedingly well-planned and carried-for story and plot-Development (the series didn't reroute, but continued on from the original -Clannad- script).
The illustrationstyle was the perfect match for the series (as it did give it its apeal and its distinctive feel.
probably one of the most intriguing, touching and tragic tv-entertainment-serie productions, ever to have been produced (overall).
i, whom can barely shed a tear, cried at atleast 4 key-moments while watching the series.
You could allways feel how the creators had really pushed to see just how far they could take; the series tragic-aspects.
anyway, really good series with a 10/10. this is a Anime you will never forget.
