Good concept, poorly executed.

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 one of the best movies I’ve seen in a very long time. You have to go and see this on the big screen.
