I don't usually write reviews but I feel the need to let the viewers know that the current 2.1 rating for this drama is MISLEADING and doesn't give justice to the show's artists and production team. Note that the 1 star ratings are mostly from Army who argue against the few seconds use of V and Jungkook's details in the show (you can find more information about it online and you can judge for yourself whether their arguments are justifiable or not).
This drama is actually a gem. Though not as star studded, it is at par - if not better on some aspects - with Death's Game. Kudos to the production team for doing a greay job in tackling and unravelling sensitive issues around life and death and then putting them on screen. The actors delivered well and the cinematography and musical scoring were on point.
Again, do not be misled by the rating. Watch the drama, instead, and see for yourself.
