It was my first horror movie which I guess is an overstatement for this film. However, one scene in particular gave me chills.
In the beginning, one of the characters held up a newspaper that had headlines reading "5 die in fire" or something like that.
Just this morning, I heard of how recently 5 had died in a fire in some Scandinavian country on the New York Times. Sure, that's a weird coincidence, but the creepiest thing about it is the fact that they had died in a fire in an escape room.
