Don't Hang Up

Even if the game-playing manipulation of 'Mr Lee' seems familiar from many other films, it is presented with real craft - and the moral commentary on the disconnect between online activity and real-world repercussion is very much of the now.

The killer seems to have a master switch to every single electronic device in the hapless pranksters' house. It's tough to take the film seriously when the unknown assailant has CIA powers of surveillance.

A formulaic story of teenagers behaving badly and getting what's coming to them.

Basically, Don't Hang Up is a hire-me sign masquerading as a slasher film.

There are familiar shades of Scream and Phone Booth in the feature debut of co-directors Alexis Wajsbrot and Damien Mace, but they also bring roving-camera flair and energy to the claustrophobic tension.

It's not a bad teenage-type drama-horror.

Don't Hang Up is a total B-movie and the characters are barely likable. What I will say is that its pacing and suspense was there for me.

Don't Hang Up is a valiant, but ultimately disappointing, addition to the new social media horror genre.

The co-directors ... work everything without emotion or verisimilitude. [Full review in Spanish]

The end does not completely fulfill its purpose. [Full Review in Spanish]
