Svaha: The Sixth Finger (2019)

This is the 2019 mystery thriller film [Svaha: The Sixth Finger], starring Lee Jung-jae, Yoo Ji-tae, Park Jung-min, and Lee Jae-in, directed by Jang Jae-hyun, who also directed 'The Priests' and 'Exhuma'. The main plot follows Pastor Park Woong-bae (Lee Jung-jae) of the Religious Affairs Research Institute, who specializes in investigating religious corruption. While tracking a new religious group called 'Deer동산' (Deer동산), he becomes aware of a mysterious murder case and delves into the truth behind the fake Maitreya who dreams of eternal life and the twin sister Geum-hwa (Lee Jae-in), born 16 years ago. Despite being a relatively niche genre, occult horror, it surpassed its break-even point by drawing 2.4 million domestic viewers and even topped the box office upon its release. While the unique worldview and the actors' performances are commendable, it leans more towards a mystery investigation than outright horror, which might bore horror enthusiasts. Additionally, the latter half's development and conclusion have been criticized for being somewhat anticlimactic.
