What did you think of the Russian folktales?

I loved the Russian folktales.  It is one of the reasons I picked this book.  It has been on my radar a while, since I am very interested in folklore.

I did storytelling as a side gig for many years.  I have not done it as much in the past 6 years or so, but I am still very interested in folklore from all over the world.  I am not super well-versed in Russian folklore per se, but I was  familiar with Baba Yaga, the Rusalka, and the Domovoi.  I have also read several tales about packs of wolves attacking humans in winter.  I did enjoy the fleshing out and updating of that tale.  I did not anticipate the direct clash between Christianity and the belief of the old gods that would drive the plot.  It brought up a lot of interesting questions and ideas.

In my culture, I can only claim regional folklore.  Although I am currently in Texas, I spent a great deal of my life in the foothills of the Ozarks, so I read and told Ozark folktales along with others.

What did you think about the folklore element?  What about folklore in your culture?
