If you're into stories about messed up teenagers who can't tell reality from their nighmarish fears, including the fact that their parents could not care the less if they live or die, you would be better off watching "The Wretched" (which provides a more coherent storyline and better acting), "Slender man" which provides much better looking actresses and a scarier monster (whereas this movie totally lacks in both departments) or track back to "A Nightmare on Elm Street", the movie that Started This All Genre (and still kicks asses).
Everything you can see in Baba Yaga is kind of "seen already, and in that other movie worked better".
