I found Farscape impossible to watch because of the main character. The show suffers because of the classic misogynistic writing where all the female characters are tripping over themselves to get noticed by the bland, aggressive, stupid, and overly cocky "average Joe" that was thrust into an unusual situation. It's extremely dated writing and as a woman, it really irritates me.

The rest of the show is great! But the main character just ruins it for me completely. Unfortunately that kind of writing is everywhere in older sci-fi. I started and gave up on Stargate: Atlantis for the same reason. I wish someone would release an edit with the more obnoxious parts removed because I can tell that I'm missing out on some great sci-fi but it's just unwatchable to me.

On the other hand you've got shows like ST:TNG, ST:DS9, Battlestar Galactica, even Lexx, where either women are treated with respect and not overly sexualized, or if they are sexualized then so are the men, and the men are kind, intelligent, and curteous, or if they're not then they're probably a villain.
