Coppelions are genetically modified humans that can withstand the nuclear radiation created by a power plant disaster which made Tokyo too toxic to live in. Years after the disaster, three high school aged female Coppelions are sent to the now abandoned city to look for survivors. The three young women have to deal with many dangers and personal issues during this 13 episode series.
Now for the review:
1) Everything, but the Coppelions, is well drawn. Obviously the animators wanted the Coppelions to look different then regular humans. However, the Coppelions look as if the animators had missed the final step of adding color to the Coppelions face and skin. This makes the character drawings appear incomplete.
2) The English dub and music is good.
3) The characters are likable and interesting, but...it's frustrating to watch them at times doing things so obviously stupid that it needlessly puts their lives and/or the lives of people they are trying to save, in danger.
4) The story occasionally has irritating flaws in logic. In one instance, a Coppelion uses a superhuman power to escape the villain trying to kill her, but instead of continuing to use this power to help her escape, she doesn't and uses regular old physical exertion which allows the villain to catch up.
In the end, if you can overlook the flaws, Coppelion has enough positive points to make it worth watching.
