Well just finished watching the last episode, definitely a tear jerker (although Clannad had me crying like a baby >_>)
Overall this was a very good series but sometimes couldn't reach greater heights due to it's short length, which I can't blame on Jun or anyone else involved and they did an admirable job with such an emotional story to tell.
It seems we'll be getting an extra 14th episode with the last DVD/BD, the seventh volume. What it'll be based on I don't know, I'm personally hoping we get to see what happened to everyone after passing on (particularly Otonashi and Kanade.) Unfortunately that's not coming out till December 22nd according to
Amazon.
Well I look forward to the next series Jun works on, whether it's 13 episodes or more.
