Firstly, the pacing is not very good, I think it has a lot to do with their decision to force two stories into every 22mins episode, therefor a lot of minor points got cut out, which hurt the atmosphere building drastically.
Then the art varies form passable to just bad, I don't know how much budged they had making this show but it doesn't seem to be much. And the overall color palette is too bright, not moody enough.
Needless to say this doesn't do justice to Ito's work.
