I was totally surprised at how great this film.You could feel your paranoia rise as the film went on and as you gradually learned the details of the real situation.

if their story seems completely bonkers, almost like a feverish work of fiction, you ain't heard nothing yet.

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

There's a more than satisfactory amount of boom-boom in the movie's trim running time.
