The series got off to a good start. It was very deep and philosophical. I teared up. Later the story veered all over the place on topics like the afterlife of pets -- a noble topic but not well done. Main characters are in and out of Hell and I am not sure why. The jury is still out on the main female character's, character. Should she be punished for running a loan shark business, or were her actions mitigated some by the mercy she showed several of her clients. I have not finished watching the series and thought about bailing several times. I was looking for some universal truths and what I am seeing is a mixture of Christian philosophy, Korean culture, and K-pop production values.
