The animation may be horrendous 90% of the time, but it honestly doesn't bother me. I find myself thoroughly entertained by each episode. Despite the "PowerPoint presentation," the plot and characters are still strong. At the end of the day, I think that's what matters most in an anime.
Animation: 4/10
Mostly terrible, with some nice looking scenes here and there.
EDIT: After watching the final episode, I bumped up my rating for this category. Not only was a scene in this is episode very well animated for season 2, but it was the best sequence of animation we've seen in the whole series so far. That has to count for something.
Art: 9/10
The character designs and coloring look great, and I'd even say it's an improvement over season 1. It's just held back by the animation.
Story/Characters: 9/10
Just as good as season 1.
Music: 7/10
Pretty average soundtrack, with a few standouts. None of the tracks particularly sound bad.
Voice Acting: 9/10
(Japanese) Good casting, and very well done all around. You can tell the VA's are putting their all into it.
Overall: 8/10
