The main interest here is the period detail. Those who make films today set in the 1940s ought to have a look and listen - then they might not make some of the mistakes of language and tone that are so common.
However, we have to face the fact that this film is a cheap flag waver. The first third drags as we go through some unconvincing stories about the home lives of the sailors, mostly done in the "chirpy working class" mode that the British entertainment industry favoured at the time. The main story is far-fetched and the Danish village is made of the cheapest painted cardboard.
During the war it was obviously important not to scare the families on the home front too much, with the result that there is little real sense of danger on the sub and hardly any casualties. In contrast, think of "Das Boot" with everyone bathed in sweat, cooped up in claustrophobic conditions, breathing foul air and scared out of their wits. It's not like that here. Despite the food and fuel running out and depth charges going off all around, everyone is pretty much calmness personified.
On a positive note, the Germans are real ones and speak correct German, which was good going for a wartime film.
