“Crash Course in Romance” (일타 스캔들)

“Crash Course in Romance” is about an elite hagwon math tutor who is so popular that mothers line up at all hours to get their children seats at his lectures. By chance, he encounters a former national handball player who gave up her dreams of competing on an international level to care for her niece, who was abandoned by her mother.

“Payback” (법쩐)

The early episodes of “Payback” held promise for a truly compelling thriller with the always great Lee Sun-kyung in the lead role. Lee plays Eung Yong, an ambitious man with a photographic memory when it comes to numbers. But the storylines get progressively more convoluted as the show progresses.

“Tale of the Nine Tailed” (구미호뎐)

In Korean folk-lore, 구미호 — which literally translates into nine-tailed foxes — are cunning creatures who live to be about 100. As they age, they grow an extra tail. 구미호 are usually young women who seduce men to eat their livers or hearts. But in the K-drama “Tale of the Nine Tailed,” the alpha fox is Lee Yeon. Once the mountain God of Baekdudaegan, he was kicked out for a variety of reasons that revolved around his love for a human woman named Ah-eum.

“The Interest of Love” (사랑의 이해)

답답해. That’s the first feeling that comes to mind when I think of the K-drama “The Interest of Love.” The entire series is about a group of broken people who can’t articulate how they feel and are in a constant state of unhappiness because of this.

“Revenge of Others” (3인칭 복수)

“If everyone decides to corroborate a lie, then it becomes the truth.” One of the characters in the K-drama “Revenge of Others” says this near the end of the series. And in many ways, it sums up the thesis of this high school revenge series, which is a murder mystery with twists and turns. And though I guessed early on who the murderer was, I didn’t anticipate the why.

“The Glory” (더 글로리): Part 1

“The Glory” had so much promise — a strong leading lady (Song Hye-kyo), a skilled screenwriter (Kim Eun-sook), the backing of Netflix’s money, and the promise of a scintillating revenge thriller. And yet at the end of the eight-episode first season — stop doing this, Netflix! — I found myself underwhelmed.

“Reborn Rich” (재벌집 막내아들)

Describing “Reborn Rich” is tricky without giving away the ending. Is this K-drama a time-traveling thriller? Or a revenge series with the poor battling the obscenely wealthy? Maybe it’s a tale of repentance? It’s all that and more. Smart and calculated without resorting to tired tropes, “Reborn Rich” offers powerhouse performances by Song Joong-ki (in two roles) and master actor Lee Sung-min (“Misaeng”), who at just 54, convincingly portrays the former’s grandfather.
