I liked this one. It had (1) somewhat different culture than the usual fare and (2) an after school special on growing up for the twenty somethings.
I liked how the family was drinking so much to mask uncomfortable feelings - just like real life families! I liked how they tried to shoehorn joy into past feast traditions when they would probably have more fun with new traditions - just like real life! I liked how all of the people were flawed - just like real life!
It was a real life Christmas that actually portrayed the reality of going back to your small hometown. You can have fun with friends, tolerate your family, start to feel the joy of becoming the responsible adult in the family, enjoy the feasting, and learn that gifts will always be mismatched. Also it shows the forced celebrations with a recipe of specific traditions (put forward by the mother in this instance) were not really the point of Christmas nor the source of joy. Communal celebrations and real friendships, conversations and support for family are more important.
