I will begin by saying that, while the review may sound scathing, this mini-series has some things going for it. If you enjoy the super-suite type mecha stuff in the vein of Bubblegum Crisis Tokyo 2040, it's graciously short, and ultimately may be worth watching for you.
The plot isn't really the issue. It's another take on something we've seen time and time again, and for that get's a mediocre score. It didn't try to reach anything new, didn't overstep its boundaries, and didn't use any lame explanations to try to change the game from similar stories that preceded it.
The main issue I had is the cheap, quick animation and art style that so many 90's/early 2000's anime series suffer from. This show feels pumped out, robotic, and just like there wasn't much effort put into it.
The characters are all takes on popular anime cliches too. The helpless girl, imprisoned and weaponized; the ace pilot who's angry at the corporation that forces him to fight, etc.
Surprisingly enough for as lazily as the show was done, whoever put the soundtrack together did a surprisingly great job. Even in parts where poor character exchanges would've normally had me saying "Oh god, get on with it." The soundtrack managed to make me second guess my nonchalance and almost want to feel what they are failing to bring across emotionally through rushed dialogue.
Not bad. Just not original. If you're in desperate need of some kids in cyber-suites killing inhuman monsters, then check this one out. If you're looking for something new, great, or visually stirring, pass right by this one.
