I watched this because I knew very little about the danish situation during the second world war nazi occupation. The story about the family is woven as a string of episodes only loosely connected with the major developments. Things do happen in the stories of multiple family members and others, but expected consequences of actions and what occurs are to a large extent absent and unexplained.
The characters of Jesper Christensen , Bodil Jørgensen and Mads Reuther make the strongest impressions of the Skovs with Gustav Dyekjær Giese and Sara Viktoria Bjerregaard surprisingly bleak despite strong developments in their life stories. All personal stories are quite shallow so it's hard to get engaged in any of them.
Unfortunately, the looseness of the storytelling inhibits the potential in the story, despite the possibilities a more held together presentation could have achieved. Therefore I don't think this is a film one must see, but the actors are not terrible and if the subject interests you it could be worth a watch. Just don't expect anything epic or spectacular.
