Both are about children piloting giant robots, while dealing with their feelings of fear, loss and despair.
Take a bunch of kids with lots of personal problems, make them fight with huge mosters for unclearly reasons to save the Earth, add a backup group with great power politic and military to help them, put in Japan and mix. Eat while it´s still hot.
