I think space sci-fi does them great when it's not just about Humans Vs Aliens.
Mass Effect did a great job at making you care for creatures of outer space..
Also, the fact if an human goes to another planet make Them the Aliens,
and this script rarely was touched on.
Like, Avatar (Blue people with tails) did it right.
But the sequel kinda missed the mark..
Anyway.
Rick and Morty did few things right.. And wrong of course. But I like when
the theme of outer space creatures are not just stereotypes or
re-hatched ideas.
I wish we had variety in the mix, like a more emotional connection to the worlds out there.
Even if I know we are too likely to never see a second sentient race that can build
shit to a higher degree than us.
