I watched a documentary the other night called Ai Wei Wei. It is the story of a famous Chinese artist who dares to voice his dissent against the Chinese government. Despite all of China’s prosperity, this documentary offers a valuable insight on how tightly things still are controlled.
Towards the latter part of the documentary you have to wonder, if not for his high international profile and support, whether his voice would have been silenced.  Without divulging too much of what happens, there is an interesting scene where they show a clip from Hilary Clinton. You get to see how people can have a positive global influence by lobbying their politicians.

The clip below is just a movie trailer, not the full documentary.
