hmm like Ryll mentioned it seems to have a nice atmosphere. The main character is a little run-of-the-mill, but oh well, so many of them are nowadays anyhow...
The animation, especially the backgrounds and skylines was awesome. The sand tank was also wicked sweet and the action had a good pace and was quite detailed.
Only thing I don't care for sofar: the writing. As if Honoka reciting those poems all the time wasn't enough we seem to have this mushy overly-prosy narration. It was really annoyingly overwhelming with the sentimental stuff. Dialog wasn't anything to write home about either.
The music is nice although neither the OP or ED are more than OK, IMO.
I'll continue with this show, i suppose, though not as enthusiasticly as some of the others.
edit to below - i really meant to say that the poems i can stomach. they actually are an interesting aspect of Honoka's character. The narration is really what bothered me.
