Spoiler alert, for those that haven't seen the movie or read the book series (or have any deductive reasoning abilities).
Allow me to set the scene. The Volturi are ready to snap the lovely little human neck of a frail little human girl. Let's call her, oh, how about Bella. The only way to save Bella's frail little human neck is for her
But then his lovely and talented sister Alice interjects, with her ability to see forms of the future that are contingent on myriad changing factors and generally wrong, and yet everyone chooses to believe her anyhow. What does she see? What possible future lands itself in Alice's vision just in time to save the day and Bella's beautiful little human neck? Well, it's this.
And this is when the entire theater burst out laughing.
Hmmm, so the whole point of whining through 3 books to be changed into a vampire is so Bella can frolic through a forest wearing clothing courtesy of the Land's End catalog?
There are no words to describe how very lame this
EDIT: Because I just couldn't resist -
