Thanks to a hint here a few days ago (sorry, can't find it anymore with reasonable effort to credit the person posting it), I watched Ukraine on Fire from Oliver Stone. As I found it quite interesting and insightful, I decided to give The Putin Interviews (also from Oliver Stone) a shot too.

Both well worth watching IMO.

That said, I think Putin is not the dumb infantile emperor the western media paints him as. The NYT article that d_eddie posted a few days ago is a speculation that would fit the picture I got from the above Stone documentaries much better.
