I watched the whole first season in one day! Not so much Sci-fi, but fantastic character development. By the end of season one you truly know all the main characters and some of the secondary ones. The only problem with the series is that where to go from here? Yes, they are on Mars and you can make episodes about the explanation of the planet, but you can only go so far, and not enough in my opinion for a whole second season. Then again, if Netflix does not renew for a second season, you are not left with an incomplete storyline.
