At the behest of a certain GAF DS9 fan, I'm deep into my first ever run through of DS9. My mid second season thoughts:
Avery Brooks is getting better, but he's still rather unlikeable as a character. In the words of Super Nintendo Chalmers: "The rod up that man's butt has a rod up it's butt."
The Ferengi are mildly politically incorrect, but you have to love them.
Something about the Bajorans rubs me the wrong way. They just aren't very likable as a whole. And the Bajoran uniforms are awful. They look like the earth-tone pantsuits my Grandmother would buy in the 80's.
The slooowww build up to the introduction of the Dominion is well done, J. Michael Straczynski is doing a great job with that.
As for the other characters:
Kera Nerys: So far, fairly bland. Suffers from Bajor-itis. Peach is not a good color for her.
O'Brien: a decent character so far, he's better the crankier he is.
Quark: One of my favorites so far, he seems like the easiest character to write for.
Odo: The "where do I come from" Data-ish stuff is a little ho-hum. I like Odo best when he's being a detective.
Dax: Terry Farrell isn't really selling me on the 300 years old thing.
Garak: Too soon to see if the hype is justified, but I like him.
Gol Dukat: Good villain, I already see why he's so well liked by the community.
Bashir: Ugh.
Overall, I'm really enjoying the show, and I'm irritated when I run out of discs and have to wait for Netflix to ship me the next batch.
I'm dreading the Worf-transfusion in Season 4, but we'll see. I'll try to keep an open mind.
