^^^ you're right. I hated that entire monkey climbing effect they had in Twilight. Plus I hated that Catherine allowed the actors to change their lines, while "Spider Monkey" is a cute term of endearment, it was NOT in Twilight the book.
I didn't know who to blame for the missed lines, and missed scenes, Melissa, the actors (who I've read some didn't want to say certain lines from the book and changed it.) or Catherine.
I hope in New Moon they just stick to the lines and scenes in the book.They're perfect the way SM wrote them. I didn't understand why they needed to add scenes that weren't in the book instead of filling the time they shot those scenes with the ones we all wanted to see from the book. I never liked the field trip scene, instead they should've extended the meadow scene with lines in the book or used the time for that scenes covering other parts they've missed.
