Execution scene
Everybody makes comments on the sex scene, but nobody made comments on the execution scene. I just couldn't watch it, I had to skip it because it was too much for me. Plus, the fact that it was played by a singer I have seen many times in music videos, just made me feel too uncomfortable.
I think one of the big issues of the movie is a strong disapproval of death penalty. I hope one day the US will put a stop to it, like most countries.
