The cinematography and direction of this movie is excellent and for that reason at least it is worth viewing.

However my understanding of the real events of Dunkirk and the truth about it was that it represented a retreat and a disaster.

Yet the film puts a positive "spin" on what really happened.

Furthermore: there are many people in the world who are unaware of the history of the real Dunkirk and for much of this picture the events come across-to me at least- as muddled and confused.

For the above and other reasons the best I can do is 6 and a half which after anxious consideration I round down to:

6/10.
