One of the main reasons I started on the path to leftism (real leftism, not the fake western one) over a decade ago. His documentary 'the new rulers of the world' provided a glimpse into capitalism and its disgusting nature.
'The war on democracy' also helped me understand how America and the west fuels disingenuous "revolutions" across the globe and how you shouldn't fall for every protest movement out there.
'year zero, the silent death of cambodia' made me realize how vicious the empire can be.
