12. Unfriended
The most recent horror movie to come out and join the found footage subgenre is perhaps the one which is likely to date before all the others - Unfriended places its emphasis entirely on the world of social media, with much of the action taking place over Skype conversations. Leaving aside the rather cynical aspect of producing a horror film using such cheap methods, the gambit barely pays off in Unfriended, which for many is little more than ninety minutes of bad actors shouting at one another on their laptops. Still, with a $40 million gross against a $1 million budget the chances of a sequel are high. Unfriended at least attempts to offer some commentary on the nature of cyber bullying, although this too will no doubt become a rather dated preoccupation when viewed with the passage of time.
