I really enjoyed the movie and I thought that Dian's character was very strong, wise and even mature for her age. in the beginning one could see that she was much more inclined to side wuth her father but as the movie progressed and she and Ivan grew to have some sort of love for one another she seemed to really branch out and help him emotionally by making him smile, being his connection to the outside world and keeping his hopes alive and she physically helps him to escape and asks her father, which is a great risk in itself upon her well being not to kill Ivan. She, to me, seemed like one of the heroes in the film. She has a great sense of pride for herself and her country, she has this appealing innocence and youth about her yet she is not naive. She has a wonderful commanding presense, quiet strength and is a very brave young woman. She really is one of the main reasone that Ivan did not lose his mind and helped save his life in so many ways.
