DVD: Incendiary

This confused melodrama miscasts Michelle Williams as an East Ender who's having an affair with Ewan McGregor's tabloid hack when a terrorist bomb goes off in London, killing her husband. The story would have to be searingly intelligent to tackle such a contentious topic, but 'Incendiary' is so scrappy it's insulting. What can you say about a script in which the heroine is shot by the police, and then, a scene or two later, the incident is completely forgotten? Nicholas Barber
