Amid the relentless churn of streaming platforms, a handful of lesser‑known series have emerged as quiet triumphs. between 2019 and 2022, shows like Kingdom, Giri/Haji, Delhi Crime and Unbelievable delivered genre‑bending narratives that also serve as cultural commentaries, according to the source list of eight underrated series.

Kingdom’s Joseon‑era zombie twist

Set during Korea’s 16th‑century Joseon dynasty, Kingdom (2019‑2020) reimagines a zombie apocalypse within a rigid court hierarchy. Crown Prince Lee Chang, played by Ju Ji‑hoon,must juggle palace intrigue while an undead outbreak spreads from rural villages to the capital. The series juxtaposes night‑marred terror with the cold calculations of courtiers, turning a classic horror premise into a commentary on power and misinformation.

Giri/Haji’s cross‑continental yakuza chase

British‑Japanese co‑production Giri/Haji (2019) follows Tokyo detective Kenzo Mori (Takehiro Hira) as he tracks his presumed‑dead brother Yuto in London. The narrative weaves language barriers, cultural misunderstandings and yakuza rivalries into a tense cat‑and‑mouse game. London‑based detective Sarah (Kelly Macdonald) and the enigmatic Rodney (Will Sharpe) amplify the series’ uneasy atmosphere, reflecting Mori’s internal struggle between familial loyalty and harsh reality.

Delhi Crime’s procedural realism after 2012 gang‑rape

Based on the real 2012 Delhi gang‑rape case, Delhi Crime (2019‑2022) portrays Deputy Commissioner Vartika Chaturvedi (Shefali Shah) leading a beleaguered team through painstaking phone‑record analysis , witness interrogation and city‑wide transport mapping. The show emphasizes procedural detail while humanizing victims’ families, illustrating the immense public pressure on investigators. As the source notes, the series offers an unflinching portrait of a nation grappling with systemic violence .

Unbelievable’s victim‑centered policing critique

Unlike typical crime dramas, Unbelievable (2019) focuses on systemic failures faced by victims. Young Marie Adler (Kaitlyn Dever) reports a rape only to encounter disbelief and invasive questioning, prompting her to retract her statement. Years later, detectives Grace Rasmussen (Toni Collette) and Karen Duvall (Merritt Wever) adopt a compassionate, detail‑driven approach that uncovers a pattern of assaults, highlighting how empathy can reshape investigative outcomes.
