How can a National Geographic special about the 90's be so informative at some points (e.g., I really did not know that the first terrorist attack on WTC, pre-9/11, was predicted by a credible source) and yet also so ignorant and poorly-researched on other points? (e.g., a conveniently-omitted detail on HOW - more specifically, WHO - suggested 'Smells Like Teen Spirit' for Nirvana? I thought that was pretty much common knowledge by now.)
