It took a lot not to sneer at the trailer for Unfriended. Surely just another low-budget, hammy, opportunist horror flick looking to hose up the undecided cinemagoers and make a quick buck. Yet, the critical reaction to Levan Gabriadze's movie has been intriguingly positive.

It tells the story of a group of online chat room friends who find themselves haunted by a mysterious, supernatural force using the account of their dead friend.

"As a way of tackling the dark and disturbing side of social networking, this is a fair effort, with the cautionary aspect of bullying having consequences coming across effectively," wrote Angie Errigo of The List.

"Perhaps director Gabriadze and writer Nelson Greaves intended to create a Social Media "Scream" and a commentary on cyber-bullying, but "Unfriended" comes across as disdainful of millennials," said Richard Roeper of the Chicago Sun-Times.

Still, it could be that Unfriended tops the UK box-office this weekend, with only the period drama Far From The Madding Crowd (Carey Mulligan, Michael Sheen) to contend with.
