The story beats pass by way too quickly; this in turn compromises the mystery aspects and makes everything solvable before the show presents it's ta-dah moments. I think you can tell no-one took this project seriously when both sub and dub voice actors sound like they rushed through it and/or just kept their first take.
I'm not suggesting a slow pace like Monster Anime; I'm just saying this story would have benefitted from the plot being taken seriously and more flushed out. Although the aim may have been to use such a serious premise to present it in a more light hearted fashion or the manga may have had a plot that wasn't so rushed.
Oh well; not like it's my demographic anyway, although I do remember being in that demographic and I would have thought the same then.
