One sentence plot synopsis: A group of unknowing people is quarantined in an apartment building which, unfortunately for them, is the ground zero site of a zombie outbreak.
Sound familiar? It should. The 2008 film Quarantine was a remake of this Spanish horror flick. And, like most American remakes, it tried to do too much. In contrast, [Rec] does more with less. Lower budget, fewer effects. But the result is something masterful. Utilizing the first person style rendered comical by the Blair Witch Project, Balaguero and Plaza have done something innovative and interesting with subjects and means that have become rather boring in recent history.
If you’ve yet to see Quarantine, I recommend you skip it in favor of the original which is, in my opinion, both scarier and more satisfying.
