Usually an infectious smile is a good thing but not if you are in a Smile horror movie, where a creepy smile is the last thing you see before a contagious form of deadly of madness infects you. The first Smile scared audiences, with an actress sporting one creepy smile in the poster and trailer, even before they saw the movie. In the original hit horror movie Smile, that creepy smile was the signal that this infection about to jump from one person, as the smiling victim commits suicide in front of a hapless soul who becomes the next victim. In Smile, we followed the path of the horrific infection as it jumped from victim to victim, but in Smile 2 we concentrate more on one person.
