Underworld

Vampires and werewolves have waged a nocturnal war against each other for centuries. But all bets are off when a female vampire warrior named Selene, who's famous for her strength and werewolf-hunting prowess, becomes smitten with a peace-loving male werewolf, Michael, who wants to end the war.

Critics largely dismissed Underworld as a shallow, derivative action-horror hybrid that prioritizes visual style over coherent storytelling or compelling characters — though audiences responded warmly enough to launch a franchise. The gap between critical rejection and enduring cult fandom is perhaps the most interesting thing about the film's legacy.
