In reply to stp:
So I've watched all 6 episodes now and I thought this was a really great series. Essentially I think it's more of documentary but the imagined Mars landing and beyond envisioned in 2033 really helps visualise what the documentary is saying. It's not unbiased in terms of whether or not we should try to go to Mars. But it certainly doesn't glamorize it either. It looks at all the huge range of difficulties from the engineering of getting there, the political perspective and importance of success, living on Mars, and even the psychological issues faced by those going there.
It seems like the whole venture is, and has been, pushed by people who are total visionaries of this world.
Fascinating series, very insightful and highly recommended. 9/10.
