What makes it different from others?

It's a mild crowd pleaser for people who are exhausted by blockbusters.

Blending excellent reporting and strong storytelling, this is a disturbing film truly stranger than fiction

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
