Critical response received praise for her performance in the film. Audiences polled by
PostTrak gave the film a 52% positive score, which
Deadline Hollywood described as "awful." Frank Hoepfner from
The Wrap wrote: "The most frightening part of
Umma is not the ghostly apparition of Amanda’s mother, but Amanda herself. Under Shim’s direction, Oh’s Amanda is haunted and taut, an unpredictable force of nature." Kate Erbland from
IndieWire also gave a mixed review and wrote: "Despite its flaws,
Umma is an impressive debut for Shim, the kind of outing that hints at plenty more under the hood or tucked inside a massive suitcase, just bursting with secrets." In a positive review, Tracy Brown from
Los Angeles Times wrote: "Think more classic Gothic horror than ghastly over-the-top occult. But that’s plenty to keep viewers such as me, who frighten easily, on edge as the story progresses." ==Notes==
