The 8th Night

The 8th Night (제8일의 밤) is a 2021 South Korean horror-mystery written and directed by Kim Tae-hyoung and produced by Gom Pictures. It premiered on Netflix on July 2, 2021 and streamed in 190 countries. The film opens with a myth: long ago a monster tried to open the door between the human world and Hell so that people would suffer. The Buddha stopped it by tearing out its Red Eye and Black Eye, the source of its power, and sealing each in a separate śarīra casket for 2,500 years.

In the present day, one of the caskets is opened and the old danger comes back. A former exorcist monk, Cheong-seok (Lee Sung-min), gave up his calling and now lives as Park Jin-su. A young monk, Seon-hwa (Nam Da-reum), is sent to bring him back to stop the two Eyes from reuniting. A strange chain of deaths also draws in Detective Kim Ho-tae (Park Hae-joon), and the story tracks his investigation alongside the monks' search.

A mysterious young woman, Ae-ran (Kim You-jung), described as a virgin Bodhisattva, is linked to a secret about seven "stepping stones". The story becomes a race over eight nights between faith, guilt and an evil that moves from one body to the next.

Under its genre surface, The 8th Night is a Buddhist story about facing what you have run from. The evil is literally a pair of eyes: it is a way of seeing the world through suffering and desire. It can only be defeated by someone who stops avoiding his own pain. Cheong-seok's return from the outside world to his old role suggests that redemption is a practice you take back up, not something you earn once. The film also presents Hell as something humans let in through their own grief and attachment. The monster wants people to suffer, and its power grows wherever people are already suffering.

Viewers can read the film on two levels:

The 8th Night is one of a group of Korean genre films that went straight to Netflix during the pandemic era and reached a global audience in 190 countries. Its most distinctive contribution is its Buddhist occult framework. Exorcism cinema is dominated by Catholic imagery, and even Korean films in the genre often lean on Christian or shamanic traditions. This film instead builds its mythology from Buddhist relics, Bodhisattvas and Sanskrit chants.

Critics' response was mixed. Reviewers praised the premise and the cast, but many felt the film did not tie its threads together, fell back on standard horror tropes and thin characters, and built toward a muddled ending. Its IMDb user rating sits around 5.3.

Audiences were divided, and the film holds an IMDb user rating of about 5.3.

• Praised: the performances, especially Lee Sung-min's brooding lead; the unusual Buddhist mythology; the atmosphere; and occasional flashes of dark humor, including a detective's wisecrack at a bloody crime scene.
• Criticized: a convoluted plot that fails to tie its threads together, thin characters, reliance on familiar horror tropes, and a muddled ending.

Overall verdict: a promising, well-acted Korean horror film with fresh lore that does not fully deliver on its premise.
