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

One of the best movies of the year! Incredible from the beginning to the end.

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.
