I havent watched the last episode yet myself, but I read moonphase's review of the last ep and anime series as a whole, and I have to agree with it. I'll probably watch it just to enjoy the animation, and see the characters in motion one last time

It was very well done within the contraints of time they had, but it could have been sooo much better. So much wasted potential.
Also, he has already read volume 9 and will have a review of that up soon. (うらやましい I havent even ordered mine yet)
