Consider me disappointed given that this is the second time they adapted the story. I was expecting it to be written well (why else would they bother) but that was not the case. The writing and story are what's holding the show back.
The villain is shit and so is the conclusion to his arc. There is a general problem with the characters and their respective motivations and there is too much (repeated) exposition and odd points in the story. You will also not get an ending as it's just a part of the manga adapted leaving you with more questions and unresolved storylines.
Now what they have been doing well is... giving you creative pantyshots (even though you don't necessarily want them) and sometimes good, creatively directed action sequences with nice sound-design. This is however not frequent enough to leave you satisfied.
