There are worse things in this life than death. Snowflake society.
As adults we all most come to accept that our lives are finite and fleeting in this life. We must come to accept that we are mortals and that our lives are, relatively speaking, short. The people in this film are acting like headless chickens at the thought of death. So what. Millions of people die every day. Death is part of existance.
If it were me, I would grab a bottle of the finest vodka, along with some diet coke, grab a sleeping bag, cuddle up in a corner, and watch the world burn. Maybe play some music.
As for the children, we must help them understand and accept death. That's it. Western society is too decadent and superficial
