Eh I’d quite confidently say Farscape is far less problematic than any other show of it’s era and a great many after it.

And humans are not superior in that universe, they once believed they were and evolved into universally hated (but really hot) hyperfascists. Bringing them down was one of the biggest eventual arcs in the show and it wasn’t done by Chriton being superior, he just had wormhole weapon tech in his head that he didn’t want and believed nobody should have.

Chriton is one of the most basic life forms in that part of the galaxy too, he’s barely more sentient than food and it’s mentioned almost once an episode. He gets by by the skin of his teeth and his only real skills are maths and making friends/pissing people off.
(I do like that he also looks like a bit of a gormless idiot too, and testament to the writing and actor as he never comes across as an entitled white boy either.)

Babylon 5 has held up better than DS9 in my opinion, like both are good but B5 is just very clearly much better. The Expanse is fantastic though I agree with you fully there.

(Btw I’m not really arguing with you about anything here, I just wanted to rant about Farscape a little as I love it dearly.)
