Historically inaccurate
In reality, British officers, not Danish ones, were in charge of the German mine clearers.
Also, the mine clearing operation itself was instigated by the British.
However, the filmmakers changed this to Danish officers in order to make the usual points about Danish xenophobia, nationalism and cruelty. They wanted to once again connect historical(?) events to the issue of today's mass immigration which many Danes are opposed to.
The same cultural marxist agenda was seen in "1864". Here, Danes once again had to see themselves represented unflatteringly in order to be guilted into accepting modern-day mass immigration and socialism.
Remember, these "historical" movies are funded by Danish taxpayers. Usually, a regime will fund propaganda movies in order to prop up support for itself. In Denmark, where non-government marxists are in control of the state's movie production funds, the propaganda has the goal of removing the nation state in favour of multicultural socialist utopia.
