I just saw the movie in the cinema. I thought they had a great setup for a lovely yuri story, but the plot swerved into a different direction altogether. I won't spoil it for anybody, but I was a bit disappointed, even though the ending is very touching. Of course, one shouldn't expect a big-name studio like Ghibli to put out genuine yuri material, since it might diminish its mass-audience appeal, but I think that there was a better story in there if they taken more of a chance with this one.
