Twilight
The vampire-romance phenomenon that began with Stephenie Meyer's 2005 novel and exploded with the 2008 film starring Kristen Stewart as Bella, Robert Pattinson as vampire Edward, and Taylor Lautner as werewolf Jacob. The love triangle split fans into 'Team Edward' and 'Team Jacob'—complete with merchandise and fierce debate. The five-film saga ran through 2012, defining a generation's romance fantasy.
