This show succeeds in almost every way: it's addictive/ entertaining, it's wonderfully designed, the characters have depth, and most importantly the plot is developed so well that there's even a curiosity to the universe itself.

I wouldn't say it's perfect, as towards the beginning (and excluding the few couple episodes), there was a bit too much filler, but it's resolved towards the end and my attention was glued to the screen.

I absolutely love the way they toy with your perception of the main character after they know they've gotten you to like him - that was executed very, very well.

One gripe is that mid-way through, death seems undervalued for the majority of people you see dying. In that way it was a bit one dimensional, but I understand that it would've been hard to portray the war in greater depth.

Those are my only criticisms, really. Having it based on European lore is also a welcomed change, as you don't often see that in anime of this caliber.

9/10.
