I already wrote up a review for the show over at
my blog so to summarize, yes I enjoyed the show quite a bit (good thing too, I did start the original thread for it after all XD). Menma being a ghost didn't bother me, all the characters had their ups and downs but (with the exception of Yukiatsu) I was able to understand and like them in the end, the voice-acting was solid, the music worked and the art was pretty to look at. What I liked best about the show was that it fit really well into just 11 episodes which, as past noitaminA shows have shown, is really tricky to do so kudos to all the writers who managed to pull this off. The show gets an 8.5/10 for me and I'd love to see it licensed in the US and get a copy of it.
