It's interesting to hear some more thoughts on this show! I really enjoyed it as well though I did have some issues with it.
I actually really enjoyed the ending as well, and the show also started phenomenally in the first few episodes, but for me it's the midsection that drags some plot points out too much that really ate away at my patience. I felt that some of the expositions, fights, and misunderstandings weren't really necessary and I would have been happier if they had cut some content. Perhaps they could have given the script at least one more rewrite to make the show shorter, and that would have really made this series something special. Other than that, the fights and the music as you said make the show really entertaining overall!
I know what you mean, sometimes it was too much dialogue, even for me. But the worst thing is that the German subs on Amazon were horrible so that I didn't understand some conversations at all -.-
