Everyone would know that her cousin Eddie took her to the range each day because she was so frightened of BR, but they cut so much out that no one would know any of that. I know they couldn't have fit the entire book into the script, but couldn't they have done some important parts? <sigh>
Well, in (very, very, very weak) defense, they did show her practicing by herself at the range. Once.
What bugs me more, for some reason (probably because I can pick locks, but can't shoot handguns worth a damn), is the way she was able to pick that lock, and so quickly. And the lock wasn't even fixed solidly in place. It was that time in the movie where it was important to show that she'd learned something, I guess.
i don't see the big deal on this, i'm currently reading the book for the 1st time. & she took the job & before that she had never picked up before. so that did follow the book i guess somewhat. they just took out the scenes showing her practice that's all no biggie. honestly that at least is not a big deal. i mean if you look at say some of the "Harry Potter" films where they totally took "Winkie" out of the films, i don't see a big deal on it showing her being good at shooting.
