Over 300,000 were on the beach at Dunkirk, but the movie showed few.
The story is about several jerks trying to jump the line for a ride.
And, one. maybe 2 allied planes prtecting the troops.
C'mon, this is a weak,puny presentation of a miracle that required many thousands to portray allied troops, and more action to give a fair repreprentation of the "real " Dunkirk.
