comment
I liked it during the first episodes, but towards the middle I started having doubts and during the last episodes I hated it. My final personal opinion is that the anime is quite arrogant: it really tries to be kind of epic, but its characters are too shallow (or just don't match) compared to the complicated story (and I have doubts as well about the story itself - e.g. a lot of missing informations, too many sudden changes of directions, ...). Potentially still worth to be watched, but be careful with your expectations.
