Where does the name Portlingrad come from?
Portlingrad is derived from Stalingrad which was a Russian city that was surrounded and invaded by the Nazis in World War II. The Russian defense of Stalingrad was one of the fiercest battles of the war and was ultimately what turned the tide against Germany. This film attempts to portray how Americans would respond in similar conditions.
Is this film racist against Chinese people?
This film is in no way racist. China is simply a country that is winning an international game of monopoly and is simply collecting something of value from a nation that has borrowed trillions of dollars from them and can't pay it back. Portlingrad brings into focus this disturbing cycle of borrowing and increasing debt while contemplating one possibility how this cycle will conclude.
So who wins?
You'll have to find that out for yourself.
