His problem was that there was too much fanservice in the fanservice anime. I think. He says "aforementioned problems." I'm not really seeing any clearly defined problems, though. Just observations like "Chizuru wants to rage Kouta," and "there's are a lot of boobs and naughty behavior." The only legit concern is that the human/spirit relationship problems were never entirely explored.
It was not a good anime: chock it up to poor story telling and waifer thin character development. Don't try to tell me it was bad because it had the audacity to include copious amounts of fanservice. It's like complaining about a Gundam series with too many robots.
