I'm just sorry they didn't use the opportunity for an in-joke with David saying that he couldn't see having kids with Blue because he found he weirdly felt for her more like a sister (since Galecki and Lewis played siblings Rusty and Audrey in Christmas Vacation in 1989).
Also just wanted to echo earlier comments about Galecki's acting. I'm a casual BBT viewer, and when the Roseanne revival started, I was absolutely shocked that I could not see any Leonard in the way Galecki played David. That made me think about all the other things I've seen Galecki in over the years, and he is an actor who fully slips into his characters, his characters never feel like "Johnny Galecki as Leonard," if that makes sense.
Someone else made a comment on an earlier thread that basically said that David and Darlene were each growing in their current relationships, fixing the mistakes they made in the relationship they had with each other. I think David's refusal to have kids with Blue showed that--old doormat David would have gone along with that to make her happy, but he recognizes that isn't the right thing for him. I think Darlene also learned to bend more in being with Ben, but she doesn't have to bend so far that she becomes unrecognizable, and I can't see Darlene thinking moving her kids in with her new boyfriend (who is also her boss), away from their father (who is trying to reestablish a relationship with his kids), is the best idea, even putting aside all the other reasons why her family needs her. To those who say, "What's the big deal, Chicago is only an hour away?!" if these people are all basically hand-to-mouth with their earnings, who would be able to afford the gas, or bus money, or train fare, or even the TIME, to be making the trip between Lanford and Chicago? I don't think Harris is old enough to drive yet, and, even if she were, I doubt Darlene has enough to buy a second car AND cover insurance so her kids could drive to Lanford to see their dad, and I don't get the impression David has a car of his own. Sure, an hour is not as far as three hours, but if you don't have the money to make the trip regardless, then that hour is still pretty far away.
I was really impressed with Lecy Goranson this season. Last year on Roseanne she felt very wooden and uncomfortable, so much so you could tell she had not been acting much in the intervening years since Roseanne ended. She really came into her own this season, and did well with the material she was given.
I'm looking forward to next season, I think there are a lot of stories still left to tell for the Conners!
