The one character namely DR smith , is almost unbearable to stand and i almost quited watching the series just because of this woman. (I couldn't call her lady) .The selfishness of her is out ballanced the whole Idea of the series.and somehow outweighs the whole chalenges The others face eventhough she is totally useless , the character ruins all the visual and narrative beauties of the series. I don't know why they have spent so much to put the whole negativity of the story on this person. She is so single minded on self preservation and without any feelings towards anyone but herself that makes it feel unreal.besides that, if you could stand this person , the show fully satisfies your needs of a show about space exploration, new terrains and habitats away from our own earth.and it is entertaining most of the time.
