When I first saw Kill Bill, that shot in the head was so unexpected, even though I read the script twice before. It was so loud, and it just came out of nowhere. It was absolutly the best QT opening, just because it was so different from his others, it wasn't "cool", or "hip". And I know it left me thinking, "Damn, I thought this was gonna be a fun movie".
Another part, was the same part, when she was remembering it in the hospital room. When the bullet finally came, it felt like it went right through your face. The sound design was definatly the best of the year, and this movie should at least sweep the tech awards at the Oscars.
