Very well executed

Plot so thin, it passes unnoticed.

Your blood may run cold, but you now find yourself pinioned to the story.

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
