This movie is simply scary, intense and wonderful! Try to think about the scariest movie you've seen... now watch REC! It will eat it alive! If a horror movie is supposed to scare the S-word out of you, make you nervous, feel akward, make you not want to sleep in total darkness, then REC is a Horror movie a capital H.
Plot: Some reporter has to make a report on what happens during the night in the local fire station. It gets a call, nothing big, domestic disturbance by some old lady living in an appartement. Nothing serious, until they get to the place and "meet" the old lady. From there... it's totally out of control, realistic and super scary! Everything happens from the point of view of the cameraman. The feeling you get from watching this thing is simply indescribable. You forget you're in a movie and can't help but feel so helpless and weak! Now that's a horror movie! You also always kind of have a slight idea of what's coming, but the movie gets you every time when you think you are off-guards. "I know what's going to happen"... maybe but you don't know how, when or why!
It makes Cloverfield, the Blair Witch Project or Diary of the Dead seem like Barney the Dinosaur or stuff your grandma would film on a sunny afternoon in Ohio. It gives goosebumps! The best first-person type of movie ever! When this movie got famous in every fantastic movie festivals around the world, Sony Pictures bought the rights to the movie, blocked it from entering the "domestic market" of North America and arranged to film a quick remake/ripoff before too many people could see it, gave it a cheap marketing strategy and threw it across the land so people could think Hollywood producers are creative geniuses... unfortunately for them, "Quarantine" was seen as a cheap joke of a movie compared to the original, even when reproduced exactly shot by shot to the original. That's how good it is! Finally, after failling to reproduce foreign genius, they are releasing REC so people can see what a masterpiece it is!
Watch it in darkness, with someone and with the sound jacked-off. Best horror movie since the "Exorcist" maybe so don't miss it! Will certainly make you believe in the power of horror movies again and feel like a child. Buy it, it's valuable stuff.
