"Jane" is a very complex movie and at the same time simple. The story is slow, have a few dialogue and repetitive narrative, just to confuse you about what was real or not.
The music was okay but was only one beat, but I want to give an 8 because of who wrote it: Flash Flood Darlings, he is a gay korean singer who have amazing songs (the genre is EDM).
The cast was perfectly chosen, I think I couldn't imagine with others actors. Lee Min Ji was impeccable and I can say that almost unrecognizable. If you've watched "I'm Not a Robot" you will understand. Gu Gyo Hwan was impeccable too, no words can describe his acting, his character. It was just amazing! I want to give a shout out to Lee Joo Young, a young actress who I think is amazing.

And I want to leave a p.s here. Please go search for Justin Lim, he was honored in the movie. The movie is similar to the life he had and the work he left behind (the club part). He was a wonderful man who surely deserved more recognition for the work that he did. Get a little time to read about. <3
