[Rec] is one of the best new horror films ever made. As it was released only 2 years ago, i'm not in the liberty of posting the video here.
If you really want to watch this film, i suggest you buy the dvd once it comes out. If you really REALLY want to watch it, search in the video area of a website that begins with the letter G and ends with the letters oogle.
