I was pretty disappointed with it. I found it too typical and too disappointing. I mean the premise and plot was pretty good but it's another anime with a really, really weak main character. I know it's so typical for the protagonist to do something so totally against what the viewer would expect but seriously. The animation style is kind of weird, the pacing is a bit off and I just didn't find it that interesting. I watched it all through expecting it to get better but it just didn't.
It's average, with a cool plot. But average execution and weird animation.
