There are two reasons I haven't seen For All Mankind."For All Mankind" has been the best show so far for me, because they make every effort of get the science right, the whole crew from sets to costumes is trying to make things as accurate as possible. It's great stuff from a Nerd perspective.
The first and more important one is that its Apple TV exclusive and I'm not getting yet another subscription to watch one show.
The second is because I heard about the treatment of Wernher von Braun in an early episode and it immediately turned me off. Von Braun's sole crime was being born in Germany at the wrong time. Von Braun also had nothing to do with Apollo 10 not landing. That was the plan from the beginning and everyone agreed with it. The way Gene Kranz dies is also spectacularly that-would-never-happen stupid. Maybe the showrunners can get the space physics right, but they seem to know very little about actual history or NASA operations.
