Whoever came up with the concept of this film is a genius or rather i would say "savage". This is not your conventional zombie apocalypse film it takes a whole new approach to narrate it.
Basically, it is a mockumentary where two parties have to decide whether a man named "Salazar" found guilty of mass murdering an entire town is really guilty or not because the photos that he clicked the night those murders took place, suggest something completely different and terrifying.
So this is basically the two parties discussing/debating the night of the deadly incident through those 36 photos that Salazar took. The narration is quite interesting and as you hear it out along with looking at the pictures, you have to imagine what happened.
The photos are enough to give you an insomnia attack if you watch it at night. However, the film as a whole might not terrify you exactly. Also, it is a very straightforward film with no twists and turns which i didn't like exactly. Nothing to talk about performances as there is not much acting only talking.
Overall, i would suggest you give it a try cuz it is a different kind of film that attempts to have a unique take on an old concept. Watch out for the photos i really felt black and white photos of demons were way more scary than actually seeing one in motion.
