I binge-watched this show over a period of 2 days so it definitely has some entertainment value, but I can see why it's not getting renewed. For one, the emotional drama between the crew was a bit over-the-top. There's no way these people would be so incompatible if selected for a Mars mission. They do end up forming form a strong bond as the show progresses, however, which makes up a large part of the character development. There are some laughable scientific inaccuracies that were only added for convenience or dramatic effect. Way too many crying scenes. For a show that tries to be woke (and I do give it kudos for having a diverse cast), there are some silly stereotypes. There are at least some pleasant surprises and the show is not completely predictable. A bit cheesy but fun, very dramatic, good characters, just not a knock out of the park hit.
