[Rec]³: Génesis (2012) shifts the franchise to a wedding setting, where celebrations descend into chaos as the demonic infection spreads. Breaking from strict found-footage style, it blends zombie horror, bloody splatter, and dark comedy, making it a cult favorite for fans of outrageous gore and twisted humor.
