Finally watching For All Mankind, and my biggest note is that this series has a critical lack of focus.
It's supposed to be about alternate history space race, but it keeps going off on tangents about women's lib and immigration and drugs and grieving.
It's like if every Star Trek episode was half about the adventures of the Enterprise and half about the mundane lives of the relatives of the Enterprise's crew.
My god, they get fast and loose with the science when the drama kicks into gear.
There were small issues throughout, but the S1 climax is just scientific nonsense.
