mostly what I dislike most about it is that after her final death, the Inu/Kag relationship didn't noticeably progress that much further. It was like her ghost always lingered between them, even after she was actually gone.
This, right here, is what bugged me the most. Especially after the crying-tears-of-blood thing... I'm like "Okay, you're mourning, understandable... but c'moooon..."
