A very nice thriller in treasure hunt mode with a pretty dark mood. I'm not too much into thrillers but I always appreciated treasure hunt movies where the characters start with one clue that leads to another, that leads to another until the end.

Here the first clue happened to be the main character's daughter's phone number found inside the head of a dead body he's autopsying. Original, morbid, a good start. The rest of the clues happen to be on an unaccessible island because of a storm so he ends up directing a random girl on how to inspect and autopsy a corpse over the phone. Again, a great idea, that's the best part of the story, pretty gross and funny at the same time.

The suspense is perfectly handled, combining Paul's current search for clues, the links to his past, his daughter's situation, Linda's stalker story, there's almost no slow part. Adding the night and storm into the mix, the whole thing feels a lot like Millenium-like nordic thrillers. There are also false clues which are very well used. [spoiler]Ingolf which is suspicious af for the whole thing but turns out to just be a convenient mean of transportation. Linda's stalker ex boyfriend that could very well have been there but is just not.[/spoiler] Great thing is that they're not on purpose false clues that would only be there because of a very precise scenario that would lead the viewer to a theory just to be able to turn it around later in the story. They're more like natural real life random coincidences, and that makes it so much better.

On the same level, an interesting part is that the whole clue hunt doesn't go at all like its creators intended, not only because of the storm preventing to go to the island, but as we can see, because [spoiler]Sadler is not dead[/spoiler]. On one hand that makes it more pressing and suspensefull.

However on the other hand, what the fuck ? When you think about it a little, what would have been the goal if all went according to plan ? A very complex and morbid 4-5 dead bodies clue hunt that would probably scar Hannah for life, where [spoiler]all the participants have already killed themselves and the main culprit, so all of it just to play a sick game of "I told you so" to a guy who just refused to break the law and lie about the evidence in a police investigation[/spoiler] ? Really ? It was worth going through all that, the whole thing is pretty extreme, that's a lot of imagination and work, and even hurt an innocent girl [spoiler]like their daughters (and as we see, it could have gone really bad for her because they fucked up)[/spoiler], even after [spoiler]already having their vengeance[/spoiler], when the only goal is to [spoiler]behave like assholes to a guy that did nothing wrong[/spoiler].

Though because the story is well written, with a good rythm and you only discover information a piece at a time, this incredibly stupid starting point is not really visible until you take a step back after the end. During the movie you're just jumping from clue to clue like the characters and it's a very masterful story that catch you from beginning to end.
