In the beginning they did have too many "stars", but they could have easily picked one or two per episode to highlight. Didn't have to be done all at once, make the intros and then take it from there. I never really liked Tasha but when they brought her back as Sela and then in "Yesterday's Enterprise" I thought it was good. They needed to work the kinks out in the first season but I don't know if they had the patience or really the time to do it. I'm just glad they worked it out and we got to see some amazing characters. I loved Worf and all the Klingon episodes. Those are some of my favorites still.
