I feel like this whole movie is an extended metaphor for how, at least in the filmmaker's eyes, Georgia has floundered post USSR.
Kote represents the post USSR world.
Notice how Lado is always going to Moscow.
The one girl's dad who is in prison, in the box that that one girl's mom keeps, there's a USSR passport (if you look closely).
The movie ends (abruptly, in my opinion), with the one girl going to see her father (some sort of reconciling with Russia)?
Just my two cents. Not that I agree with the filmmaker's ideas, but I feel that the film can be interpreted to work on that level.
