A faithful, but slow and unimaginative adaptation, I think... not the best of Aksenchuk's films.
A much weirder adaptation of Krylov's "The Crow and the Fox" can be found in Irina Smirnova's The Song of the Cheese Spirit (1997) and (though it uses completely different text, aside from mocking the whole thing) Aleksandr Tatarskiy's Plasticine Crow (1981).
A much weirder adaptation of "The Cuckoo and the Rooster" can be found in Andrey Hrzhanovskiy's In the World of Fables (1973).
