Tormented

High-school horror movie in which Darren (Calvin Dean), an overweight asthmatic nerd, is bullied to suicide one summer by a gang of friends. Intent on revenge, he returns as a zombie ghost and invents increasingly imaginative ways to kill his tormentors.

Karl French, Financial Times: In effect Friday the 13th meets Skins, the UK teen soap opera, this is brisk and, considering the budgetary limitations, technically impressive. (Verdict: three stars out of five)

Nigel Floyd, Time Out: The late '70s high-school slasher movie gets a Facebook-era makeover in this sporadically gruesome but non-frightening British horror comedy... Scriptwriter Stephen Prentice and director Jon Wright have their finger on the teen pulse. Sadly, their solid storytelling, attractive cast and modish updates are let down by a lack of scares and jokes. (Verdict: two stars out of six)

Kevin Maher, the Times: Finally, though the qualitative bar for execrable homegrown comedy-horror was recently set at ground level by Lesbian Vampire Killers, here is a movie so inept and ill-conceived that it manages to scrape a place for itself directly below that particular abomination. It's got murders, party scenes, texting scenes - and some of the worst line-readings in the history of cinema. (Verdict: one star out of five) ·
