Chris Hormann’s review published on Letterboxd:
This plays out like a documentary to begin with as the postman for an isolated village in Russia delivers the mail and introduces us the various characters in the village. However once the postman starts to hallucinate a grey cat at night, things take a more absurdist turn and the various relationships that the postman has with his fellow villagers - characters such as the village drunk nicknamed "The Bun" and the local beauty and solo Mum, Irina endear themselves as much as our postman who seeks the latter's love.
Andrei Konchalovsky takes untrained actors and helps them make their characters utterly believable. Plenty of humour on show (of the laugh out loud variety) and some lovely scenery - it may drag in parts but it shows an unfamiliar (to Western audiences) slice of life in rural Russia.
