Forever. Begins. Today.

What do you get when you combine teen drama, vampires, and a cult following that makes even Hogwarts fans look apathetic? Twilight -- the biggest thing to hit the horror-romance-fantasy genre since a kung fu cheerleader named Buffy.

Based on the best-selling series of books by Stephenie Meyer, Twilight tells the story of a young woman, Bella Swan (Kristen Stewart), who falls in love with a handsome vampire named Edward Cullen (Robert Pattinson). Lucky for her, this particular bloodsucker is on a strict no-humans diet. His friends, however, are not, and it’s up to him to save Bella before she ends up demon dinner.

The film opened Friday, and drooling fans everywhere are already sounding off about expected sequels. If it’s anything like its literary counterparts, there’ll be plenty of blood to go around for a long time to come.
