Itaewon Class is amazing. I literally adjusted all the scores of my completed dramas in order to accommodate my rating for Itaewon Class. Among the six remaining dramas in the 9.5 list of my profile, is Mr. Sunshine and Live -- which I consider co-top 1's. I firmly put Itaewon Class as my 2nd best drama watched ever, and it's not because it was lacking in any way, but quite the opposite. It's just that the two dramas ahead of Itaewon Class made me cry more :)
This drama had everything, and I mean EVERYTHING. From a dark-skinned character, transgenders, corrupt officials, and more. This drama tackled racism and gender discrimination at some point which are issues in South Korea. All I can say is that this drama is out of the norm.
