"Mackenzie Foy is cute, but I think Renesmee should be younger," JSYK reader Shan posted. "Yeah, she grows fast, but a nine-year old?"
Valid point since Renesmee ages at rapid speed both in Bella's womb and once she's born. In Breaking Dawn, Bella grows seriously concerned about what will happen to her daughter -- who's half human -- if she continues at that rate. However, Renesmee doesn't grow as old as Mackenzie in the book.
Then again Robert Pattinson
is 24 playing an eternal 17-year-old. Should Breaking Dawn have cast Renesmee younger?
