This show speaks to me. Sometimes I feel like the world is falling apart, that there are too many tragedies happening all the time, that it's so tempting to numb yourself to all of them and to grow bitter and hard. I root for the Garveys (and Nora) because they are fighting so hard to beat back that numbness, to stay sane and retain their humanity in a world that has gone mad.
The Guilty Remnant is a warning about what could happen if you give in to that temptation. And Jarden is full of people who are putting their heads in the sand and pretending that everything is fine.
The Garveys (and, in real life, most people, I think) are in the middle of those extremes. It's a powerful allegory.
