The story gets a very solid six. I find the set up fairly interesting, especially since I don't really care for vampires in general. I really wanted to rate it a seven, but there were so many parts left unexplained, which will probably be shown in the third season... if it ever gets there.
The art was outstanding to me, and it's what I expected from Wit Studio. Definitely, check out the Blu-Ray if you can. The animation while airing on tv has some bad quality, but it's still pretty great.
Although I thought the soundtrack was fair, I really did enjoy the English tracks on it. I also love the first season's opening the most. The song for the second season's ending was beautiful, even though I couldn't watch the ending since I just wanted to skip to the next episode.
The major downfall of this show are the characters themselves, especially Yuu. He is insufferable. It's almost like the mangaka was trying to create the most annoying character, and combined every protagonist in Shonen Jump - and Kirito from SAO. I really liked Shinoa, but the second season. Jesus Christ. Why would you not follow orders from your superiors when you're in a vampire apocalypse and everyone's lives are at stake? The entire squad bothered me to no end.
Props to Mikaela for being the best damn character in the show, though.
Overall, I really did enjoy the show. I ended up binge-watching season two as soon as I finished season one on blu-ray. It is a mediocre show, yes. But I definitely think it's a good time waster. If a third season does come out, I will be watching it, even if it is just for Mikaela alone.
