Story 3/10:
The story is incredibly convoluted. I don't mean that it was hard to understand, because they did give relatively clear explanations for the events. The problem is just the sheer complexity of the plot, while managing to lack in substance. The story attempted to tell a lot, but many of the plot points were unnecessary, anti-climatic, and gimmicky.
Characters 3/10:
I had a huge complaint about multiple characters (in-fact, my biggest complaint about the show), but I cannot even brush on the reason why without huge spoilers.
Tone 7/10:
I did like the tone throughout much of the show. They didn't try to force comedy, romance, etc. in places that didn't call for it. They let the serious scenes be serious and the lighthearted scenes lighthearted. It wasn't fantastic, but it refrained from significant faults.
Setting:
At times I liked it, at others I didn't. That's as much as I am willing to say in fear of spoilers.
Art 6/10:
The art style itself is nothing to behold. The animation is fine but in no way superb. There are a select few scenes that stood out particularly well though. Not in the details or fantastic action scenes, but instead in capturing significant meaning in a single shot with well placed and scaled objects and 'camera' (so to speak).
Sound 6/10:
Not much to say one way or the other. Fairly repetitive soundtrack, but usually fitting. The voice acting was fine, but was hurt by annoying dialogue (specifically, the large amount of times they screamed each other's names during higher action scenes. It's nitpicky, but got to me in a couple of episodes).
Enjoyment 5/10:
As I said with the art section, there where a few particular scenes that were done wonderfully. So much so, that despite being bored for a majority of the show, I'm still glad I watched it.
Overall 5/10:
I think my reasoning is clear. There isn't a single aspect this show excels in, and it undoubtedly has it's flaws. To be entertained by this show, you need to enjoy lots of plot turns. I don't mean plot twists (where they take what you thought you knew and change it), but pure turns. The plot likes to stop at certain points, and just move on to something utterly new with no relation to previous events. These plots do not get intertwined, instead they simply get mashed together. Sometimes, they altogether annihilate the importance of previous plot-lines.
It's a pass for anyone who does not care for a fantasy/sci-fi for complexity of plot alone.
