So there’s this movie called Rusalochka, pretty much a Russian version of the Little Mermaid by Hans Christian Anderson. Now, don’t be deceived while this does have songs and seems all happy and cheery, it isn’t as joyful as Disney’s version.
If you can get past a movie made in 1976, then I suggest you watch this. It’s a beautiful piece that needs more attention.
