Story: 10--a good story, especially for so few episodes. Yes, the general storyline is a classic one, but it's a storyline that works, which is why it's been used so many times.
Art: 8--at the beginning I remember thinking that the art could have used a few more frames to smooth out some of the movements, but overall it's animated in the usual style for the newer anime, and the action scenes are done really well. They knew how to create tension with the visuals as well as the storyline and sound effects by zooming in on something and omitting the focus. Really keeps you watching.
Sound: 9--consistently throughout the series, I was amazed at the background music. It set the tone perfectly for each scene without making the view actually notice it until the director wanted the viewer to notice. Also, the ending song is my newest favorite (will be listening on repeat for another month). Sound effects were good overall, though most are the usual mech anime sounds (hydraulics, gunshots, metal, etc.).
Character: 10--Great character development. They structure the story so that you really invest in the characters, even though the anime is so short. Very realistic characters, flaws and all. At times you want to hate them, at times you want to just hug them 'til they suffocate. (o.O moe?)
Enjoyment: 9--absolutely loved (almost) every minute of the anime. I usually go for happy anime (Shugo Chara anyone?), and too much strife mid-series can permanently turn me off of a series. Great beginning, great end, it's the middle you have to watch out for. So, I docked one point, but still, it's a 9/10.
Overall: 10--period.
