The war has been raging between the vampires and werewolves (or Death Dealers and Lycans, respectively, if you prefer) for centuries continues in this sequal. The film traces the beginnings of the ancient feud between the two tribes as Selene and Michael try to discover the secrets of their bloodlines. All of this takes them into the battle to end all wars as the immortals must finally face their retribution. This good and somewhat unique movie is also a dark Romeo-and-Julliet story. Also, it's more of a science-fantasy/adventure movie rather than a horror film.
