This series is a combination of real National Geographic documentary and fictional drama. I thought it would be primarily a fictional account of a manned visit to Mars, so I was thrown for a loop when both actors and actual people involved in the space program were being interviewed as though this was a real voyage. I personally did not care for this mixture of truth and fiction; I found it hard to decipher which information to believe. Also, their transitions back and forth between present and future were confusing, making the story hard to understand. This show is a pass.
