An interesting and differentiated horror movie in the "gore" style. It is above average for the genre. It started slowly, but after half it became interesting, maintaining a tense atmosphere, a little frightening and claustrophobic. The atmosphere is good. It can be divided into two parts: before and after the cave. You sit on the armchair during the exhibition with that feeling of agony and distress. It escapes from the usual clichés to the genre, having an unconventional and surprising ending. There are some logic flaws in the plot and the characters, but nothing that compromises the story. The curiosity is to see the cast practically all feminine. It's worth as entertainment. I recommend it to all lovers of horror art.
