Without spoiling anything, what movie SHOCKED you to the core?

Movies based on actual events tend to stay with me for a long time. CLEVELAND ABDUCTION (a TV movie from 2015) has bothered me since day 1 when I learned that three young women had been abducted and held against their will in a man's house for over 10 long years. That man was a monster!

The Boy with The Stripped Pajamas. Oh my god.

The Truman Show. I was going crazy weeks after I saw it. But it might not have the same effect on you, since I'm generally pretty weird. hahaha
