I agree with both of you. I loved the show. I think the characters grew as the show eveolved, but found Tricia to be both confusing and unnecesary. I would assume it was a play to amp up the sexy and possible get a Galatica fan or two. Better than most shows on cable, but hey how many shows last more than a couple season these days.
Shame, it was quality TV. Worst TNT move since they cut the Gary Cole cop show. That was good old fashioned entertainment.
