The problem with shows like this one is that they're so one sided to their own political causes and ideologies that they refuse to be honest about certain topics and consider that their opponents have any legitimate views, as anyone to the right of Ken Clarke is considered to be a fascist to them.
Your view on George Soros are irrelevant to this; this is a poorly made, researched and put together documentary that seems far more concerned in providing good PR for the multibillionaire - of who is too controversial a figure to deserve such a simplistic view - as well as dismissing anyone who has worries about the big financial and business interests he represents as either kooky conspiracy theorists at best or on par with mass murderers at worst.
And it runs the racket on such smearing, particularly in the insulting way it portrays Hungarian Prime Minister Viktor Orban - a man I don't like - and his rightful campaign against mass immigration as hateful, simply for correctly pointing out Soros' hand and encouragement of such a policy (something the documentary refuses to touch, despite how well recorded it is, can't imagine why).
And it isn't limited to Orban here; more moderate conservative types like former Brexit Party MEP and its current leader Nigel Farage and the American conservative news network Fox News are similarly sneered at and slandered, which is not only insulting in and of itself, but given that you could be imprisoned for not paying to watch this garbage is unforgivable.
Avoid at all costs, and get some actual information on Soros, whether you like him or not. This is a borderline hagiography of a heavily controversial figure in business and politics, and slander against any of his critics, who are lied about beyond all recognition. Shame on you, BBC. Shame on you. A waste of time and energy from all involved.
