Holy crap, I saw this in the movies in Spain when it came out. Christ I left my heart back there at the end of the movie, I HATE spanish movies one out of 20 are good, this was one of those few. I really liked it, and I didnt sleep the next two nights.
Then as always and american dir has to say, hey you know what, lets make the same movie, sound familiar? Grunge, Shutter, REC, Mean Machine, the eye and so forth.
Oh my, this was a bit good! I had sort of high expectations for this one, due to the wealth of quality horror coming out of Spain at the moment but I wasn't prepared for how good this actually is. It's got an interesting build-up, leading to a real Zombie fest before the last five minutes, which were sublime and rather excellently done.
This is an absolute MUST-SEE!
A competent and occasionally clever exercise in reverse-siege zombie-horror, with, at its heart, an Umbrella-style experiment gone every bit as horribly wrong as these experiments typically go. While not extraordinary, this is an effective little freak-out of a film, and the closing sequence discloses one of the neater specters of the monstrous alien in recent memory. I mean cinema. I mean, something.
It's fresh, original&terrifying, thats why they make a shitty, added effects& unnecessary scenes&dialogue;'americanized' version out of this. Its fast pacing, effective shots&scenes, blair-witch-like, zombie movie.
