DVD: Tormented, For retail & rental, (20th Century Fox)

Tormented opens with the funeral of a schoolboy who hanged himself following a bullying campaign, but it's by no means a po-faced issue drama: the dead boy is soon striking back at his persecutors as a James Corden-lookalike zombie.

Each killing is so inventive and so shamelessly silly that viewers will gasp and laugh in the same breath, but, despite the film's horror-comedy hijinks, it's probably the most nuanced big-screen portrayal of comprehensive school since Gregory's Girl.
