I was unsure if I should rate it 5 or 6, and in the end decide on 6 (and still have my doubts about it)
Detailed breakdown below:
The story has somewhat interesting premise and a bit unusual settings. It starts interesting enough, however, after 1/3rd it stumbles and starts having problems. Roughly at this point anime suddenly decides that it is now the time to explain the world in great detail, while the idea is great, it feels forced. Somewhere between half-way and 2/3rds the series decide to use the most cliched device possible (you'll know what I'm talking about it), and run with the idea for several episodes, which results in a rather tedious "arc". The anime has trouble properly handle tragic, sad or dramatic elements - those simply fall flat all the time.
Art:
It is good. The closest things I can think of are El Cazador De La Bruja or Noir, except it is much more detailed than Noir. I think I spotted few frames with cheap CG lighting strike, but that's just a few frames during the whole series. Mechanical designs look good, characters are fairly detailed, backgrounds are well drawn.
Sound:
Decent music, some battle themes are interesting.
Characters:
Characters do not really develop over time. Main heroine is a bit amusing at times (she's an archetype), but she has that annoying habit of obsessing over her origin. I understand that she would have "What if I didn't exist", or "Maybe it is my fault" thoughts, but when this happens several times per episode at really short interval, it gets really annoying.
Enjoyment:
Starts off great, feels drawn out at 1/3rd, uses cringe-worthy plot device in the middle, and has annoyingly predictable events near the end. While I liked the beginning, I was very annoyed by the story flaws later on, especially close to the end.
Overall:
It is decent. I would say it is definitely worth watching because of unusual settings and visuals, but I think it would've been better without story issues.
So, it makes sense to check this out if you haven't seen it already.
