Tokyo Magnitude 8.0
Another great new series for this season. If I were to compare it to something, it would be those shows on Discovery/National Geographic where they show what might happen when an epic natural disaster strikes. As the title suggests, this series shows what might happen if a magnitude 8.0 earthquake hits Tokyo. But instead of just having the story narrated, Tokyo Magnitude 8.0 shows it from the perspective of a pair of children -- the siblings Mirai and Yuuko, and a woman they met just before the earthquake -- Mari, as they try to make their way back to their homes.
The animation is top-notch, as it is done by Bones (who also did the old and new FMA, among others).
