The biggest, and possibly only, failure of Gaza: Doctors Under Attack is that the circumstances of its broadcast threaten to overshadow its content.
A brief recap: this film was first commissioned by the BBC, only to be dropped when another documentary – Gaza: How to Survive a War Zone – sparked a furore over impartiality.
The abandonment drew uproar from within the corporation, scorn from the wider media and the inescapable sense that what started as a vital piece of film-making had devolved into yet another navel-gazing referendum on the purpose of the BBC.
Thanks to Channel 4 picking it up late in the day, Gaza: Doctors Under Attack now exists in the world, and it has never been more evident that this is a work that demands to be seen.
