I think most research on what happens when people witness a crime as to whether to intervene or stay away is that most would stay or walk away. But what happens if it's family and there's no time for decision making. What are the percentages for either of those innate reactions? So in this case you & your family are suddenly faced with a life threatening avalanche.
Personally, I would have liked the script to pursue that angle more and less of the family squabbles.
