The writing is awful and the characters are very stupid. A complete waste of time.

The Netflix description of this movie promised that this thriller set in a cavern would be another "The Descent" or even "The Cave". Unfortunately, I was sorely disappointed by the end results. True, the movie looks good, with well chosen locations and expert cinematography. But the good looks don't hide the fact that the movie is extremely slow and dull. It takes about two-thirds of the movie before the reported horror finally rears its head, and what horror there is doesn't happen to be very interesting or horrific. Also, the horror is dispatched in a pretty quick amount of time. What happens before the horror starts is even worse. There are plot elements such as a discovered tent or a person in the distance that are brought up but NEVER prove any significance. Also, none of the characters are particularly likable or interesting. The only reason why I am giving this movie two stars instead of one is that it's mercifully short, just 77 minutes long. At the end of the movie, there is a declaration that there will soon be a sequel. I think I'll pass on that opportunity.

Three friends - Adrian, Charlotte and Viktor - head out into the Norwegian wilderness to explore a cave. They are all experienced at this sort of thing and have planned well. Relationship issues - Charlotte is with Adrian but she and Viktor used to be a couple and he still has feelings for her - complicate the expedition. Moreover, someone seems to be following them, even in the cave.

Reasonably interesting. The cave scenes are well shot and are suitably claustrophobic. Quite intriguing and tense, especially towards the end. Good plot twist too.

Decent, but not great though. The relationship side was clumsily handled and there are one or two plot developments that don't make much sense, or could at least do with a bit of explanation.
