Very nice. As David Pitchard said the dresses, uniforms, interiors are very much in detail as they were in that time. Many things reminded my grandmother and her house. I also liked that the whites were shown very human and patriotic what I haven't seen that much in Russian movies.
That is because until the late 1980's the movie production was controlled by the Communists who would not put the Whites into good light. There is even a part in Boris Pasternak's 'Dr. Shiwago" which mentions the Whites in a positive light, however that exerpt was banned.
