2.5 out of 5 stars
Fine production values and acting and shot deliberately in a drab and grainy way, the film is so soaked in history that it looks like a 1912 soap opera recorded on an old VHS tape. The initial setup is predictable melodrama; and it is only when their campaign got kicked up a notch the film comes alive, turning into a more engaging thriller by the end. But I suspect the reason why this worthy, historical event has not been made into a film before, is not only because it is a hard sell – but also because the truth is an undramatic process that doesn’t really light up on screen. And despite writer Abi Morgan’s admirable attempt, she was unable to elevate this into something more than a respectable Sunday afternoon BBC drama with a dose of Streep thrown in for good measure.
