I'm going to be brutally honest with this review, but I'll start with a few caveats. For one, I watched the whole thing. For two, there was a fair amount about this anime that I really did like and enjoy. And lastly, it did EXACTLY what it set out to do, and did it as well as could be expected.
I just wish I had known more about this freaking thing when I started watching, because I was bored OUT OF MY MIND all the way until somewhere halfway through all 13 extremely long episodes.
Because this is a story about redemption, forgiveness, and sin. Don't be fooled into thinking this is an awesome anime about angels. Nobody has super-powers. Nobody flies. Their wings never get any bigger. The main character can't even run properly.
And don't get me started about the main character. I wanted to kill her. I hated her with a passion that anime rarely evokes from me. She was so pathetic and awful and moronic that I just wanted to reach through the screen and strangle her. The other characters weren't any better, but at least they didn't evoke such levels of disgust and fury from me.
I really probably wouldn't have had such intensely negative feelings about her (and to a lesser degree the others) if I had known some of the things I know now about many of the characters' "pasts". Suffice it to say that they're as far from perfect as you can get while wearing a halo around your head. These are the people who have really screwed up at life, and are being given a second chance to do right by themselves.
For the first half of the anime, this was a very strong and opinionated 2 out of 10 anime. By the end I was feeling it actually worth of the 8 out of 10 that it's rated on this site. I took a modest average of that and came up with 6 *fair* for this anime because of many of the following reasons:
The story was excruciatingly slow and boring 99% of the time, the art and animation was inconsistent and out of date, the sound was just a bunch of extremely sad and jarring off-key piano music meant to make you feel sad and tense, the characters were beyond awful (although they finished strong on that note), and ultimately I have no idea how or why I was able to push through to finish this thing considering my enjoyment was on the level of self-harm during the first half.
So yea. 6.
Watch it if it's rainy out and you have half a day to yourself to eat and fuck off and scream at the screen.
