run4yourlives sums up by feelings about this particular incident very well.
However, I'm uncomfortable with the way Wikileaks has couched the release of this video (the editing, the title, and the url used to promote it). It's agitprop, and in the long term I think it undermines the ability of leaked documents like this to enter the public discourse and (possibly) effect change.
My advice to Wikileaks if they want my continued support is to stick to what you're good at: enabling whistleblowers to anonymously release documents that may serve the public interest. But let Michael Moore handle the filmmaking.
