Sharing the review, a fan wrote, “What starts off as a natural-disaster survival thriller film suddenly veers into sci-fi territory (not a spoiler, just a heads-up about what this movie isn’t actually about). The visuals are underwhelming, though the performances are decent.”
Another fan gave the movie a solid 5 on 5 because of its story that delivers a mother’s relentless pursuit for her child. Sharing the same, a fan added, “Not even a catastrophe can shake a mother’s love.
