Deep down, we all hate clowns. They're loud, in your face, and rarely ever funny. Plus, their face paint always make them look like they're frowning and angry. Using a scary clown in your horror film feels almost like cheating.

There have been many scary clowns, but none take the cake like Pennywise. Played to utter perfection by Tim Curry, Pennywise succeeds as both a regular clown and a homicidal one, which is key when it comes to giving kids nightmares for the rest of their life. 

If you're a kid, just keep telling yourself, "It's not real. It's not real." If you're an adult, just keep telling yourself, "It's not just a giant spider. It's not just a giant spider."
