This anime suffers from epic first episode syndrome, just like Ergo Proxy does.
The first episode of this anime was such a cool experience, with the experimental camera angles and the action and the animation, it was EPIC. I was so excited to see more.
And then it became boring!! Sorry, but I am not really into political warfare a lot of the time and that is what this series turns into. You'd think the vampire angle would keep things interesting but it really didn't do it for me.
I wanted to like this way more than I did, but it did not click with me :(
