Research question pertaining to the film Mugabe and the White African?

We watched this doentary in my English comp cl and were asked to come up with a research question to write our papers about. I'm having a hard time coming up with one on my own since we are usually given the question by our professor. I'm also pretty ignorant when it comes to global issues. Anything having to do with Zimbabwe, land reforms, Mugabe, human rights, or dictatorships that could be related back to the film would be the best, but anything helps! Thanks!
