Frightening how something mundane like Chatroulette can go wrong. Chatter makes use of viewers' empathy to feel and experience what Liz is going through. A little bout of jealousy in the beginning sparks it all for viewers only for it to end bloodily and gory. This as well is another use of the "vulnerable" girl in a horror film. Despite its commonalty, the film's effective use of viewer empathy still gives it a solid 4 stars.
