@tsarstepan,
I just went to see Twilight: Eclipse with my daughter. All I can say is - spare yourself.
It was so long and so silly and five minutes into it I was thinking, 'Why should I care whether Bella ends up with Edward the vampire or Jacob the wolf?'
Problem is, even though I told my daughter that the writers didn't make me care enough about Bella to believe that entire armies of vampires and werewolves should unite to protect her, she obviously still expects me to go see the next one with her - she said, 'You'll see - in the next one all is made clear about why Jacob imprints on Bella and her baby (no baby in this one - apparently the half vampire/half human baby appears in the NEXT installment).
I can't wait!
