Hazel said all of her class has seen KDH (actually 2 classes that regularly mix and combine with a total of 42 kids in 4th through 6th grade). She's been singing the songs, writing down the lyrics so we can sing too and sketching different characters. It's interesting to see fads come and go through schools. This is the first one I've seen that seems pretty nationwide. I wonder how popular it is in other countries. I love watching foreign films and shows on Netflix and I assume they are the biggest streamer worldwide in number of people and different countries.

If you need more YouTube video's about this here are two I've enjoyed:

Mostly about the Korean words in the movie, but some about the mythical creatures: https://youtu.be/qCmpU3ssip8

A nice interview with the writer and co-director: https://youtu.be/KXBD2fU-ohg
