None of the characters are believable. In fact, most of them suffer from an increasingly common movie disease - they behave like entitled, petulant, morally self-rigteous people from the 21st century, who openly show their contempt for people in authority instead of people living in the 1940s under Nazi occupation, and fearing for their lives. This increasingly common type of movie character is designed for ignorant viewers to identity with and say to themselves "oh yeah, give it to 'em! Tell them off! Yeah that's what I would have done if faced with Nazis!" No, that is fantasy. People behaving like that would have long ago been sent to prison or a concentration camp or shot dead in the street. I'm tired of waching supposedly historical period films where the people dress like the time period but talk and behave like they're in the 2020s.
