In short: Nothing new, nothing to deep but some overlook for those who are not initiated in how City of London works (like the trading outposts of old to circumvent laws). You get to follow a minister who tries to make a difference by trying to partake in the broken shadow system. The change won't come until people rise up, the model for UK in the modern world is to be a tax haven for the rich which both centralises informal power, influence and crime.
The docu. downplays the state of affairs (with width of it all) and how some nations (two or more) have tremendous funds to destabilise nations who do not follow suit in corruption and crime.
In longer: The actual number mentioned (32 Trillion i think it was) of money in tax havens is a drop in the sea (the initial ICIJ report mentioned $62 trillion, which later got corrected to 30 something, which later got lowered once more - formally the error was counting the same money several times, this later got named the Panama leak - that is ONE regional instance of tax avoidance). The point in time when ICIJ got access to the information was right before the leaks of the totalitarian shadow gov. et al surveillance systems came out, it then took a year to be released to the public.
The debt throughout the world would probably be history if those who benefit most from society carried their part, or at least as much as the average company/worker. Constructed ("Natural") debt is used to suppress social mobility and keep a lot of people in line (not all).
Pro's Basic run-over over City of London. Message - You as an individual have to act (with today's surveillance the cost is higher than ever) Realistic outlook - unless YOU act, things will not change, the people are many, many doing little will over time beat few doing much Naive outlook, which is needed, doing good in a bad world is tough and requires it.
Con's Shallow Limited outlook on cause of events ("...bird of the nigh" shadow gov. and the creation of it) Sound is used to manipulate the viewer (to effect; bad actions = bad music/sound...).
End Notes: 7 is still a strong grade, one star for the effort and 1 to encourage people looking into the subject. The information about City of London could easily have been made a lot deeper simply by looking around casually for it.
*This review has been edited since the last spellingcheck by me, can't recall properly what was written but half a sentence had been removed and several spelling errors inserted. The vast majority disregard text with spelling errors and its content - probable reason why it would be modified to contain errors (check my reviews that are still up and read them over now and then - every time checking them for errors - so i do know if those were previously correct or not.
