I thought the show's take on the grieving family was good. Usually in these kind of things, you're dealing with a mother and father who have lost everything when their child is murdered, but this show is dealing with the reality that this family hasn't lost everything, and how this is going to effect the two young children who are still here, how the parents are (or are not) going to explain it to them and try to give them a normal life while dealing with this unimaginable tragedy. It's an idea that hasn't really been much explored, especially on tv.
