I've read "The Wonga Coup" by Adam Roberts, so I already know a fair bit about some of the colourful characters described in this documentary. There is some interesting footage of conflict zones and some brief mini-interviews with some of the people involved. It is interesting. But ultimately this documentary just rambles around with little particular direction. I kept thinking to myself: okay, so where are they going with this? In the end, after an hour, it didn't really lead anywhere.
(Also it is quite an old film and so now totally out of date and does not cover the "contractors" working in Iraq and elsewhere. This is not the films fault, but just so you know this is c. late 1990s. It is relevant as a historical insight of the dealings of the mercs in the earlier post apartheid period however.)
