Good start, but then it gets ruined

One of the most extraordinary films you will see this year. Take that as you want.

The film never slows down or bores, plunging from one harrowing sequence to the next.

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
