Personally, I was quite surprised to actually enjoy this. I was just dragged to the movie theater (never seen the teasers, never even knew this movie existed) but I loved this.

1) It's quite funny. So, Kim Jahong died a heroic death and was said to be a saint spirit(?) so, he goes on the afterlife with three guardians of death to go through trials to see whether he has sinned in his life. But the trials are like the normals trials in court in the real world and the prosecutors are quite dumb and funny. Heronmak is also quite rebellious and Jahong doesn't really listen well to the 3 guardians of death.

2) The CGI is great. it's almost game like (which I like) and the fights are epic. I must also point out the outfit designs are on point, especially the 3 guardians of death. Heronmak's weapon is also one of the coolest weapons I've ever seen in movies and games.

3) The actors were great and fit their character well.

4) The story also touches on the hardships of life and relationship between family, which I didn't expect at all but I pleasantly enjoyed it while crying nonetheless. There's also some twist and turns.

This is my review. Maybe I think highly of it because I didn't expect this at all but this is one of those movies that I thoroughly enjoy.
