[REC] 2 (review) is a Godsend as far as sequels go. Even though it takes place in the same virus-infected apartment building found in the original Spanish film, it doesn't retread the same ground. It charges forward guns blazing, evolving and re-inventing itself whenever and where it needs to. It's not as scary as the first film, mind you, but its energy is as infectious as the fictional disease that turns the innocent into raving maniacs. And now you can see the first five minutes of it from the comfort of your own...whatever you're sitting on while you read this!
The video comes by way of the French site Allocine and should give you a nice taste of what the movie is about without spoiling anything. Check it out:
