Over the years I’ve seen some very well done documentaries on CNN. A while back, there was a series on the Kennedys that was honest and a few months ago I saw one they did on Gilda Radner which was touching and very nice to watch.
Looking forward to seeing Apollo 11.
And for breaking stories all over the world, CNN usually has the best coverage as it is happening... before they can start adding their editorial and political agenda to it all, they're usually quite good, and generally better than the competition.
