Immortality is a strange notion. It gives you the power of denying the inevitable: death. But it also brings with it the pain of outliving family and friends. This is the dilemma that haunts Bella Swan (Kristen Stewart). Throw in a love triangle with a vampire and a werewolf, and you have the Eclipse plot.
A slew of killings hits Washington state. A vampire is amassing an army of newborns - vampires in the first few months of infection - to hunt down Bella. Newborns possess the strongest thirst for human blood.
Caught in a bitter war for centuries, the Cullens and the Quileute tribe must put aside their differences to protect Bella. She's in the middle of an awkward tug-of-war between her vampire boyfriend Edward Cullen (Robert Pattinson) and the buff Quileute/werewolf Jacob Black (Taylor Lautner).
The love triangle is reinforced visually by positioning Bella physically between her two suitors. She is the force that pulls them together and the wall that maintains the peace.
It's difficult to say which are more human: vampires or werewolves. Edward may be more intriguing, but Jacob's charisma makes him easier to relate to. His youthful arrogance brings a human quality to his role. You can't help but root for him to win Bella's heart.
