I expected something like "The Lives of Others", found the topic fascinating. There are several problems with this movie however. First is the lacking historical realism. "Kamila" is a name that only got popular in Poland in the last years. The protagonists speak very contemporary Polish. The way Kamila dresses doesn't come from the 1960s. The authors clearly had access to historical images and it's strange they didn't base on them.The second problem is the main heroin. She's too pretty and she's pretty in a very contemporary way. She doesn't look or behave as women did back then. Also the actress' acting is simply horrible, she didn't manage to portray the doubts and psychological struggles of a woman that leads a double life.The film has too much pathos in it. In the main original story the movie was based on the writer died of cancer. In the movie, he's beaten up and then probably murdered. It's as if the authors were trying hard to make the story even more dramatic than it was. The result is over the top, hardly watchable.Then there are problems with the script, which is just too obvious, doesn't show any psychological dilemma. Characters aren't realistic, were written just to represent specific attitudes towards the Communist Poland. Seweryn's and most other actors' acting was really good, but the movie doesn't deserve more than 3-4 stars.
