Policemen as defector, rather than defender, of the law is a common theme of crime movies (particularly those from Hong Kong), therefore it's hardly any surprise or delight when watching GRUDGE (2021). The revenging sibling plot can be found in BLANK (2019), so the ending is kind of revealed in the first scene (To be frank, the original Turkish title "KIN" is a giveaway). Nevertheless, this movie is well-produced, with good acting, and not a bad choice if someone desires to enjoy a movie from Middle East.
