The kindest word I can use to describe this series is..mediocre.
It was about the halfway point when I realized I was watching something that gave me no joy. I stopped for awhile after that and then came back to finish it just to say I had. None of the characters are interesting. The story is a mess leaving anything of purpose at the wayside.
There is no substance here. In fact I can't even think of more to say, but this review thing is forcing me to write more about an anime that has little to say about it.
