1) The original lost in space had a doctor who was mix between Amy Poehler and Hamlet. A trash talking robot, the kid from twilight zone who could melt you with his mind and a handful of forgettables. There was no legacy here and if there was, it wasn't in the characters or story - it was in the setting. This reboot has done a much better job creating a rich setting, with the Resolute, the conflicted robot, explaining initially why the Jupiter was lost, putting the Jupiter 2 in proximity to other survivors and create a much more dynamic environment.

2) Diversity shmiversity. I'm far from an SJW, but I don't see the cries of "oh no diversity". Maybe because I don't live in the west (where this social divide seems to prick more ears and hearts), but I felt the mothers dominance in the marriage was very clear. Her husband had essentially abandoned the family for his job, she needed to step in to fill that role - not because she is alpha, but because he was willing to step away from the family and seemed willing to divorce had it not involved separation from his kids. Also, yes Judy is not white, so what, she is John step-daughter from Maureen's previous marriage (that's the official explanation). Given how well Judy and Penny relate as sisters, I had no problem with this. Why should I, step-families happen. In fact that makes the show more relatable, not less.

I'm not saying the show is brilliant, but it's remotely kid friendly (no sexual or extreme violence). It is faithful to create the sense of wonder that the first series did - but with more realistic intonation. I'm not sure I'd recommend it, but I'm not panning it for diversity issues either. I'm also, not sure what the "writer" issues are. Kept my attention.
