A group of photogenic college kids ring in New Year's Eve by contracting a mysterious infection and trying to tear each other to pieces in Antisocial – a new Canadian horror film whose anti-technological subtext is as subtle as an axe to the temple.

The premise is straight out of a Cronenberg production: A social-media website is encoded with a rapacious, mind-melting virus, but the message has all the depth of a Tweet: #The Internet Will Kill Us All.

In his feature debut, co-writer and director Cody Calahan shows a talent for conjuring up hallucinatory imagery, and there are some startling sequences amid the predictable plot twists. With hope, next time out, he'll write – or perhaps seek out – a more worthwhile screenplay.
