Seeing the most popular and highest rated K-dramas matched up against each other helps give even more context for what was super high profile when it aired due to so many viewers tuning in. In a Gallup Poll ranking of the most popular K-dramas for the last 5 years (2016-2021), the pinnacle remains the grande dame herself Sky Castle which singlehandedly put jTBC on the contender stage. In second place is tvN‘s fantasy romance hit Goblin, and the two dramas are actually not that far apart. After that it’s another jTBC drama The World of the Married in third, followed by Crash Landing on You, and rounding out the top 5 is Moonlight Drawn By Clouds. It’s totally warranted as these dramas were uniformly accepted as big major major hits when it aired. The second half of the list starts with When the Camellia Blooms in sixth place, then Romantic Doctor, Teacher Kim first season, and worming its way on the list in eighth/ninth place is Penthouse season 1 and 2, and in the tenth spot is Mr. Sunshine.
