Simple and well acted, it has tension enough to knot the stomach.

The plot isn't so bad, but the pace of storytelling is too slow which makes people bored. Certain moments are so obvious and unnecessary for the main plot. I would've fast-forwarded those moments if it was an online streaming. The ending looks like implying a sequel, not sure if this movie will get one

This is ultimately a movie about the very bad things that can happen when we don't address our unease, when we just try to brush it off, whether that's to fit in or to preserve our self-image.

The film's masterful storytelling did its job. The message was clear. No need to overdo.
