Review of Quarantine

They won't let us out.

Arguably on of the most realistic horror films I've seen. The fact that it was a remake of the Spanish horror film [REC] still did not erase the fact that this was a film worth watching. Despite being nearly dark for most of the film, "Quarantine" still delivers a horrifying dish of terror, mainly due to the superb acting of its main character, news reporter Angela Vidal (Carpenter).
Angela and her cameraman, Scott Percival (Harris) are assigned to follow a group of L.A. firemen on their rounds. When the firemen respond to an emergency call in an apartment, Angela, Scott, the firemen, and the rest of the residents in the apartments are unwittingly pitted against an unspeakable horror which eventually threatens to consume them all. Without any contact from the outside world, Angela and Scott are forced to fight for their lives, as each of the apartment tenants slowly succumb to a mysterious disease which seems to be transmitted through bites, scratches, or other forms of physical contact which involve the mixing of blood. The resulting beings are bloodthirsty, and hungry for warm, human flesh. As the sun rises, nothing is left of the people inside the building. The only clue as to what really happened has been recorded down to the last horrifying second by Angela and Scott.
I remember Jay Hernandez (who plays fireman Jake) previously starred in another horror film (if my memory serves me right, it was Hostel) so it was a comfort to see a somewhat horror veteran in this film. The rest of the cast, although virtually unknown, contribute nicely to the flow of the film. Eerie. Scary. What would you:)
