Daniel Ott’s review published on Letterboxd:
So begins Hooptober 5.0
The entire experience would work as a simple claustrophobic survival thriller but then they go ahead and add that extra something far fouler on top of it all to keep things continually ramping up.
Outside of Sarah and Juno, the group doesn't get much development but have fairly distinct personalities and their friendship chemistry feels believable, even if we don't end up necessarily caring about their fate.
It's a tight 100 minutes that successfully cycles through tried and true horror motifs to keep you on your toes.
I recommend the 'Unrated' version that contains the original ending that was altered for the US release.
