I have to admit I was fascinated by the framing, color, composition and the great value of the locations. Every aspect made the story more compelling and thrilling.
But to be honest the finale was too much of a coincidence. The story develops great at the beginning, with a group of characters that have to keep everything in secret because of their past. But the last two episodes that arc failed, it seemed like the killer got involved as a coincidence, it seemed like that person wasn't even involved, like if they got no other solution.
Other than that the story is terribly Misogynist. Women letting men treat them like nothing through the whole movie, not empowering at all. All the women in the film were seen as weak, stupid and helpless.
