Saw this a few hours ago. I thought it was good - much better than the mainstream reviews suggested, and managing quite well to show at the same time that Wikileaks is important but Assange is a bit of a creep. Too much sympathy to the US Government in my view, because that's where all of the human interest stuff is located; no human interest in the people who are the victims of what the US government does or sponsors. The Kenyans who are victims are pretty much faceless - we don't build any emotional connection with them before they are assassinated.
But a a good film for the most part, and engrossing despite the length.
