Worst Ever? 20 Of The Lowest-Rated K-Dramas Of All Time
Namu Wiki determines the lowest-rated K-Dramas based on if the viewership rating is 0% for more than two episodes. So, even if a K-Drama rated well on average or did well in its first couple of weeks, it could still get some of the lowest ratings.
Check out 20 of the lowest-rated K-Dramas from the past eight years below. They might surprise you.
1. Bubble Gum

12. Sweet Munchies
Despite the 2020 JTBC K-Drama Sweet Munchies‘ storyline relying on gay representation, it is unfortunately not substantial enough to truly be a BL (Boy Love) K-Drama.

When Kim Ah-jin (Kang Ji Young), a television assistant director who is one of his regular clients, asks him if he knows a gay chef who could star in her cooking program, he decides to lie about his sexual orientation and gets the part.

This show which aired on Wednesdays and Thursdays has a recorded lowest single-episode rating of 0.8%. At the time, it beat previously low-rated KBS2 K-Dramas Manhole (2017) and Lovely Horribly (2018). Even its average rating of 1.7% was considered the worst until it was broken by the MBC K-Drama Oh My Ladylord…
14. Oh My Ladylord (also known as Oh! My Master)
Oh My Ladylord is a rom-com about screenwriter Han Bi Soo (Lee Min Ki) and top actress Oh Joo In (Nana), whose seemingly unromantic lives truly unfold once they become roommates.
Oh My Ladylord is considered an example of “Drama Kingdom” MBC’s “downfall” due to its incredibly low ratings. Despite its prime time slot on a free-to-air TV network, it averaged a 1.6% viewership rating, which is the second lowest for a drama in its position. The KBS2 K-Drama Love All Play ended up breaking the record, but they tied with the lowest-rated episode of 0.9%, which in Oh My Ladylord‘s case was Episode 12. Welcome still has them beat with the lowest figure of 0.8%.
15. Love All Play (also known as 493km for You and Going to You at a Speed of 493km)

2021 JTBC K-Drama Nevertheless aired on Saturdays and is adapted from the popular Naver Webtoon of the same name. It focuses on a toxic romance between Yoo Na Bi (Han So Hee) and Park Jae Eon (Song Kang).
Despite its high 2.5% rating at the beginning, Nevertheless recorded its lowest rating of 0.994% with Episode 8.
18. Idol: The Coup
12-episode 2021 JTBC K-Drama Idol: The Coup aired on Mondays and Tuesdays. It starred an ensemble cast of EXID’s Hani, Laboum’s Solbin, Han So Eun, WJSN’s (Cosmic Girls) Exy, Kim Ji Won, Kwak Si Yang, and Kim Min Kyu.
Ironically, the K-Drama focuses on the struggling K-Pop girl group Cotton Candy which needs one more shot before being disbanded. This K-Drama also wasn’t a hit as it recorded a low of 0.354% with Episode 7. Its average rating is only 0.601%.
19. Never Give Up
ENA’s 2022 K-Drama Never Give Up (also known as There is No Goo Pil-Soo) tells the story of two different men: middle-aged former boxer turned chicken shop owner Goo Pil Soo (Kwak Do Won) and 20-something app developer Jung Suk (Highlight‘s Doojoon), who end living and working together. It aired on Wednesdays and Thursdays and is available to watch via Netflix.
The 16-episode drama, unfortunately, was never able to climb into the 1% range (its finale recorded at 0.958%). Its premiere recorded its lowest rating of 0.45%.
20. Extraordinary Attorney Woo
You probably think we made a mistake right now, but wait and let us explain…
As you probably know already, this other ENA K-Drama that was released internationally on Netflix focused on rookie attorney Woo Young Woo (Park Eun Bin), who is on the Autism spectrum, and her relationships with her family and coworkers as they solve legal cases. It aired every Wednesday and Thursday in the summer of 2022.
Extraordinary Attorney Woo actually did set the highest ratings in ENA history. Its finale not only received a phenomenal 17.5% nationwide rating (According to Wikipedia, this is the “eighth highest-rated drama in Korean cable television history and seventh highest-rated television drama by number of viewers,” by the way) but it was a huge hit internationally too, including in the U.S. Still, Extraordinary Attorney Woo premiered with one of the lowest TV ratings that year with only 0.9% rating. Thanks to word-of-mouth, it became the popular, award-winning drama we know and love, and it is planned to have a Webtoon and second season. Let this be a lesson that it’s not always how you start but how you finish!
