Terrible acting, screenplay and direction.

Brilliant and touching

While it doesn't offer any answers, it both thrills and makes you think.

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
