The Clear Critique YouTube channel poses a common conundrum: The hardcore viewer that appreciates the artistic merit of horror, but isn't actually *scared* by much. For those of us cursed with almost psychopathic levels of nerve, there just isn't much in the world we find disturbing. So when a movie can reach past the defenses and grab you by the core and shake you, even a little bit, it's worth a special nod.
On a side note, the "terrible American remake" the reviewer mentions of [REC] is Quarantine, which, according to Wikipedia, opened at the #2 spot behind... Beverly Hills Chihuahua. If there's a more humiliating thing that could happen to a horror movie, I don't want to know about it!
