REC is zombie horror brilliance! REC is one of the best found-footage and zombie movies ever made. The panic, chaos, and terror that grows and spreads through a small apartment building as residents fall one by one to a zombie plague is overwhelmingly suspenseful and believable. REC starts slow but exponentially builds into a bloodcurdling frenzy with horrified characters frantically struggling to survive. This low-budget horror film belongs in the hall of fame for creativity and genius in the genre. I saw the American remake, Quarantine, many years ago, which is very similar to this film, but REC edges Quarantine with originality and a franchise of 3 other films following it. Any zombie or horror fan needs to add this to their watchlist immediately!
