Hi! Welcome to the site. Did you find it while looking for a place to vent about PJ's movies, and not be accused of being several unflattering terms (I got called a B**** the other day on another site....it was rather funny.
) If so, you're in the right place.
As far as your final question goes....yes. And I have no idea why.
Idiotic costume design...come on, I know Middle-Earth wasn't exactly modern day medical techniques, but I'm pretty sure leaving hammers in somebody's head sounded like a bad idea say, the day after the elves awoke.
