With regard to the moves and their influence, if that's the case, then it helps a bit. I just thought having a school shooting was a cheap move to invoke intense emotion in the scene. I found it very poorly directed. When I say dead, I mean from the perspective of her parents, not that the character is actually dead.
In the end, my wife and I were so intrigued by and enjoyed the narrative so much for the first 6 or 7 episodes that we watched them straight through in one sitting. It was only the end that I felt did a poor job to deliver and tie things up even with a second season planned.
