If we talk as a simple cartoon, then the usual such a normal cartoon, in color is very similar to the Soviet adaptation of fairy tales. There is nothing that perverts Russian cartoons of the 2000s, everything is done properly, let the children watch.
However, if we talk about the work of art in general, it turned out poorly. Interpretation shows a huge compression of cultural information into a very small text. The cow is a totemic animal, a first ancestor, a symbol of all ancestors of the genus, from whom one can draw wisdom. But they are in another world. They can be visited through a mystical experience – passing through the ear of a cow. This is a metaphor of the rite of initiation and a description of the path through the stars (the cow's eye was called the bucket of a small bear). In modern terms, a portal brought the heroine through space to the world of her ancestors, from whom she received help, wisdom and strength. Three sisters are moiras: past, present and future. Havroshka possessed the magical power of the word (conspiracy) and put her sisters to sleep. Only the future could damage the ancestral world – the cow was slaughtered. However, the ancients believed not even in the transmigration of souls, but rather in the cyclicity of life, a series of transitions. And the first cow becomes a tree. It is not even possible to say that she was killed, because she was not just a living being, she was an idol and passed into a new state. The cow (ancestor) told her never to forget, and the fulfillment of this covenant allowed the heroine to create a prosperous family. It is an ancient formula of life and has been observed for centuries. Also in the story there is an indication to get help from trees. Today, this is called the ugly word "energy vampirism", and ancestors believed that obtaining strength from a tree, a connection with nature - the key to health and a long life. This isn’t my personal interpretation, it’s from culturologists.
Unfortunately, almost none of this was reflected in the cartoon, except that the image of parents in the other world was deciphered. I believe that this fairy tale deserves a much more serious and non-childish adaptation. With a full decoding of images for a rootless modern viewer and better graphics.
