The story basically is about a widower father and his two daughters who often had disputes. The father got really ill near Christmas, so he and his two daughters spent the Christmas in their old family home.
By some miracle, their mother who passed away several years previous suddenly came back to help straighten things out.
I suppose that this is a fantasy that everyone who lost a loved one has, and this movie was a nice exploration of what could happen in such a case.
Aside from that, this movie has excellent moral values and is perfect for the whole family. Subtly but surely, this movie illustrates mainstream Judeo-Christian values. It successfully showed us the problems of addictions, abortion, fornication and obsessions without showing us the ugly side of humanity -- an extremely unusual feat.
Those who do not like being preached to would likewise enjoy this movie, as even though it is a movie of morality, it does not try to indoctrinate or preach.
This is the perfect movie.
