Yes, but the space part was pretty good. The fictionalized conversations and so on, who knows, but the general thrust of it was accurate.
Wernher von Braun was a very pivotal character in the US rocket program, missile development, beating the Russkis to the moon and by default not losing other technology races. However, I am glad that they shine a bit of a light on his Nazi activities. I do believe that his only ideology was rockets, but in the pursuit of his ideology he was as fanatical as anyone else in Nazi Germany at that time. Most people who were SS Majors, party members, met on multiple occassions with Hitler and Himmler, employed slave labour to make their equipment, and were instrumental in building and firing what were nothing less than terror weapons against helpless civilians were not given government jobs in the U.S. after the war. But we are perhaps lucky that he was.
Someone told me that he wanted to title his memoirs "I shoot for the Moon", but someone suggested it be subtitled ...But Sometimes I Hit London".
