Shocking, people do your research!
I took the stupid decision to watch this movie with my 2 kids without knowing anything about the movie, I knew it was about a girl and trying to save her best Freind, plus Tilda Swinton is one of my favourite actress ever. I was shocked of the amount of swearing, but that was nothing.... the second part of the movie was so shocking that even myself, as an horror veteran, can't take.
SPOILERS:
The rape scene had me jaw dropped, my 12 year old looked away while I cover my 7 year old face and years. Then of course the slaughterhouse was the complete horror package, including the heart breaking baby scene at the end that had all of us crying our eyes out.
My son is already vegetarian so this was even more shocking for him. It was totally my fault for not knowing nothing about the movie and thinking it was a fairy tale story. People do your research.
