This show offers so much. There's a lot of action and thrills. Along with some frightening and sad moments. Honestly at times it kinda reminds me of Game of Thrones or the walking dead. Because you never really know who's gonna die. The story is really good and it has really developed throughout the four seasons. Theirs lots of characters to like and dislike. Their designs all look great and the back drop with the cities and landscape looks beautiful. The only thing for me is that there's a few parts in the story and some character mood changes that I just don't really appreciate. But it's just about a perfect 10. Thus why I give it a 9. Honestly I believe this show will be in my top 5 anime. But that's my opinion...
