I don't like comparing two dramas just to favor my favorite one, but just this one time, I wanna say, "THIS WAS BETTER THAN SQUID GAME".....O! MYYYY! LORDDDDD! THIS IS HOW A PSYCHOLOGICAL THRILLER IS DONE....
Every episode depicts a new dark element of our society. But it also shows some humane sides. We, as a society have fallen soooooo low that we've started normalizing ABSOLUTE satanic behaviors, yet some people still have some what of a human side to them. Greed, lust, wrath are forbidden for a reason, they not only rot our souls but also the core of our society.

THIS DRAMA COVERS A WIDE ARRAY OF EMOTIONS, felt by both characters and the audience.

Overall, I highly recommend this drama if you can handle a huge amount of psychological and physical torture.

p.s, I gave a low score to music because there's something VERY CREEPY about those songs in this drama.
