Lars Sieval’s review published on Letterboxd :
The Horrors of October 2014: “Hoop-tober” Edition!
Martyrs is something else. It's about revenge, torture and reaching the Martyr state. The acting is good but the best thing is the make up. That scarred woman looks brutal. Just brutal. The story is about a group of people who abuses people and tortures them to get them into a Martyr stage. We follow one girl who has been abused and escaped at a young age and her friend.
All I can say is if you haven't seen this one yet, it worth your time. Also don't eat while watching this.
