  1. Around about the third act, the picture does what no self-respecting virus ever would -- relents, turns confused, and lets our immune system fight back with thoughts of its own, with distracting cavils about the logic of the plot and the slightness of the themes.

    The look of the film, shot on digital video, is haunting and gritty. The cleaner, prettier look of 35mm would have detracted from the immediacy and sense of foreboding created in this artful blend of sci-fi and pseudo-realism.

    Cinematographer Anthony Dod Mantle, a veteran of low-tech Dogme films, work wonders with a digital camera, pausing to take in the beauty of the countryside or an eerily empty London…It's virtuosic without ever quite being showy.
