Really enjoyed this. (Reviewing after season 2) First season starts you off thinking it is just another one of those mission to mars shows that there have been a couple of over last couple of years or so. Quickly descends in to a sci-fi show about the origins of mankind and having already destroyed one planet (Mars was once in the habitable zone millions of years ago) an artificial intelligence left by the previous inhabitants of Mars tries to stop the same happening again on earth. Would really reccomend this if you enjoy a good sci-fi/space drama.
