Watched the U.S.A.'s 2022 Umma (1:22:45), about a Korean-American woman named Amanda who left her abusive mother after their family migrated to America. After the mother dies, an uncle traces Amanda's whereabouts and drops off her mother's ashes and belongings at her farmhouse. Amanda herself has a daughter. Both undergo apparent hauntings and possessions by the deceased.

Quite strange that Taiwan's 2022 Incantation is also about a mother, a daughter, hauntings, and possession, and that, in both movies, the mother-daughter relationships verge on the dysfunctional, if not neurotic. Both are cases of folie a deux (madness of two), a clinical psychological term describing an intense paranoia shared by two persons. In Incantation a curse implanted in the subconscious could very well explain the negative karma that befalls the mother and her daughter. In Umma it is possible to conceive of the hauntings and possession as metaphorical projections of an Asian-American's subliminal guilt for turning her back on her cultural identity; I would not be surprised if all Asian-Americans undergo this at some point in their lives.  

This is not a vanity movie. Sandra Oh is a fine actress, regardless of who produces her movies. The problem is that fine actresses should never be given horror movies as vehicles for their acting. For starters, fear is the easiest emotion to convey; even supporting performers, bit players, and extras can be adept at it. The world has yet to know what a serious performer Sandra Oh is, and she should be given real roles that she can sink her teeth in.
