(Spoiler Free Review)
Minor objectionable content (TV-14).
Hmm where to start....? This show is pretty bad, definiately a below average anime. The animation and sound are awesome, but the plot and characters are a mess! Definately a piece of charcoal in a velvet pouch. Reminds me of bad, but popular shows like Noragami or Deadman Wonderland. There is no progress toward the original concept. The plot is stagnant. Character motivation is weak at best. Many important characters, plot devices, and events were not addressed. In some cases, the side characters are more elaborated than the main characters.
Maybe this is just me, but I care way more about the plot and characters, then about the animation or sound budget for any show.
All in all, I rate this anime 4/10 -- Below Average, primarly because of the anime budget.
