It comes not even close to show how bad the movie really is
-Kirk and his brother are celebrating christmas in a gigantic mansion (the director's house)
-His brother feels bad that they are wasting so much money with christmas because he keeps thinking about some poor kids he saw one day
-He feels like we are all losing the actual spirit of christmas and that the holiday become too commercial
-Kirk says that he is wrong, and expends the rest of the movie lying to his brother about made-up symbolism. The christmas lights represent the cave where Mary and Joseph hid, the presents represent the city of jerusalem, the tree represents the cross, saint nicholas was a barbarian who used to go around beating people with dubstep music
-Kirk's brother forgets about the poor kids and dives in the presents, everyone starts dancing to hip-hop
-In the end Kirk says that we all should just lie to our families about the actual meaning of christmas just to stop them from feeling bad (this is not a comedy)

I mean sure Christmas got too commercial but that's just despicable.
I feel bad for you that you had to go through this garbage.
