It was pretty decent. Unlike some of the other documentaries, they actually talked to Zuck a bunch and even showed the house that was their "office" in the company's early days... Unfortunately, it won't be rerun in the next two weeks, but I think it's likely CNBC will rerun it in the future. I didn't realize why there were so many scenes from London until I saw the credits. Its looks like it was done by a British company or for/by the BBC.
