I'm giving this movie 10/10. It became one of my favorite movie & below are reasons why: First, it's original, different from other horror movies, which brings interesting story, where crowd of few people seek historic relic & treasure. Movie was very eerie & creepy, especially when they go deeper & deeper close to hell. Some very strong & intense moments. Atmosphere was also eerie cause whole movie happens in damn catacombs. If you have Claustrophobia I don't recommend to watch it. If you're fan of movies like The Tunnel(2011) or The Devil's pass, you gonna like it.
Under 17 requires accompanying parent or adult guardian 21 or older. The parent/guardian is required to stay with the child under 17 through the entire movie, even if the parent gives the child/teenager permission to see the film alone. These films may contain strong profanity, graphic sexuality, nudity, strong violence, horror, gore, and strong drug use. A movie rated R for profanity often has more severe or frequent language than the PG-13 rating would permit. An R-rated movie may have more blood, gore, drug use, nudity, or graphic sexuality than a PG-13 movie would admit.
