If you've read the book(s) then you'll understand how important it was for these characters to be cast by the perfect actors. Whoever did the casting did exactly that. You can't help but sigh the first time, and every time, you lay eyes on Edward and you become attached to Bella and all the others as well. This movie may be for teenagers (I have about a dozen teenage girls in my world) but this 42 year old mom feels like a teenager herself when she enters the world of Twilight!
