Can't click the 'spoilers' button, because there are no spoilers.
This is about 15 or 20 minutes of total material, spread over 8 episodes. There is all kinds of fake drama (clearly faked, how do you surprise your dad when 2 or 3 guys with cameras walk in). Nothing exciting, nothing gets found, it's just boring. The 10 minutes of the 20 that are dedicated to Gordon Cooper are kind of cool. But you see that in the first episode. The other 7 episodes each add about 1 minute of new material, and rehash for the other roughly 39 minutes of show (discounting the 20 minutes of commercials).
I wish everyone would refuse to watch this so they stop making these kind of shows. This should have been a 1 episode documentary, nothing else.
People giving this a positive review are nothing more than fake reviews to get the ratings up.
