They delved into some of the most depraved and disturbing aspects of human behavior, leaving a lasting impact on the audience long after the credits have rolled.

1 – Dogville (2003)

The film is shot like a videogame, with electronic music, graphic violence, and vibrant colors that give us some insight into the mindset of the characters.
