Interesting premise, really bad writing, cheesy soap drama drivel, each crew member has a history of OTT emotional turmoil, 2 years of a crew training together & none of them trust, like or respect each other yet they're chosen to spend 3 years together travelling to Mars, each character is completely unrealistic, absurd by any idiots standard, complete lack of any scientific detail.
If this were a movie it would be on the sy-fy channel playing after midnight for the insomniacs, boring incredulous claptrap for the moronic viewer.
Yes it's bile, yes the low scores are justified, it is boring & bland.
