Good honest film....but

Rating: Null/10 (29 August 2019)

Loved this film and paid tribute to real heroes.
Just a couple of irritating things. The warships used were not British and it was obvious.
The worst picky issue for me were the Container Cranes in the background when the docks of Dunkirk were shown.
Containers weren't invented until late 50s early 60s and these cranes quite a while after !!!
