IÂ saw this at the film festival last year because IÂ had read a description of it which said no more than "reality TV crew gets attacked by Zombies and they don't stop filming " and this was truly the scariest movie IÂ have ever seen in a cinema.
At points you are will be actually pleading for the characters to not go into that room or turn on the light because of the sense of realism you get.
This movie is in Spanish but you soon forget about reading the subtitles and focus more on the beautiful TV reporter scream in horror and you can basically know what the are saying with reading the subtitles
The Zombies are scary as hell as they chase the crew up and down the building.
This is a lot better than the Hollywood remake quarantine and if you like horror movies with Zombies in it and what the crap scared out of you watch [REC] guaranteed to make you jump
