REC is a gem of a movie. It's a well-executed found footage film, which I find to be rare. This is my favorite Zombie movie of the 2000s decade. REC is fast-paced, claustrophobic, gory, and has great scares. You can purchase this movie digitally or find it streaming, but, at least in the US, the English dub is forced, and it's not great, so I'm glad the physical copy doesn't do this. It's so good the US remade this as Quarantine, but why watch Quarantine when REC is great.

I hate found footage but this is an exception, and the release is great with some cool extras 

On of the best and creepiest found footage movie.

One thing about this film... During the making of the film, none of the actors knew what their next day of shooting would be, so every day was extremely anxious which created a extremely tense set.
