Yes it has a hyperbole. Russia is not that ruthless or cruel. But I didn't watch it expecting to see a real life unbiased and objective documentary. So in that regards I was not disappointed.

If you watch the movie with a light mood, expecting to watch a thriller with twists and good acting and beautiful scenes you will be entertained and amused.

I believe sometimes our expectations are unrealistic. I used to have unrealistic expectations of movies, tv series or any kind of art. I was constantly unhappy. When I lowered my expectations I started enjoying art again.

This is a 2 hour movie you are most likely going to have fun and end up with a smile and happiness and enjoyment.
