No, they don't have classification as far as I know.

Crimea is even more beautiful and picturesque .

Well, about the movie itself - I found it rather kitschy and at least disjointed.
The harsh ending is not in line (IMO) with the rest of the film. The NKVD officers weren't exactly sort of Bronx gangsta dudes, especially during the Khrushchev era named "ottepel" . The physical disability of hers was to add some 'outcastiness' and compassion, where just alcoholism would suffice. All in all the idea behind the movie seems to be to make another " Burnt By The Sun" Directed by Nikita Mikhalkov and it failed.

PS my first post here - so hello all !
