Other reviewers have said it is the best "found footage" film they have seen, I would go beyond that and say it's the best and scariest horror film I have ever seen, by far.
I definitely recommend this, if you are looking for a terrifying film then this will not disappoint.
[REC] is definitely one of the better zombie movies. The claustrophobic atmosphere was really effective.
This movie is an experience. It stands out because it has strong characterization, and a rather well orchestrated buildup.
Sadly, it was also remade into the complete and utter piece of shit "quarantine". Unfortunate because I really used to scare the shit out of people with this years ago :) but now they go "oh wait I've seen this" but it was the horrid remake.
In closing, if you liked "The Descent" (2005) and other modern style violent thrillers, treat yourself to this. It has a 7.6 on imdb with 56k votes for a reason.
I agree about the last part. The rest wasn't that scary.
Shat my pants watching this in a dark room at 5 AM
