I've seen every documentary on space and the Challenger that have been produced. Many were bad, some were good. This four part series is pretty good, covering familiar ground and likely a good refresher for anyone who lived through those times, or more beneficially for those younger people who are just raising their awareness and understanding of this troubling catastrophe.
The producers did use the "it's going to blow up" scenario as the dramatic leverage (e.g. cliffhanger) here. I think its overuse is justifiable, though, given the fact that if the NASA decision makers had listened to the whistleblowers and weighed the risks, the crew would have been pulled off Challenger until corrective design changes could be made (or at the very least, until a launch attempt in February when temperatures were above freezing could be attained).
One remarkable thing to note: Americans were proud of our accomplishments then, and the early footage of the shuttle launches proves it with various video segments showing people actually waving flags and saying how proud they were of their country. It is sad to think that that very footage seems so alien now, given how bad many citizens of America love to trash their own country.
