"Roseanne" is back with that same infectious laugh, same wry sense of humor and make no apology style but now tackling decidedly modern issues. ??? if the ratings are any indication, the revival of "Roseannep is a smash hit with more than 18 million viewers. You're ruining my life. You all suck. I ain't seen that movie in 20 years. Classics really do hold up. Reporter: Since the show's finale 21 years ago, Roseanne and the conner family -- What's up, deplorable? Reporter: Diving head first into the issues and conversations happening right now across America. From the rising cost of health care. Funny story our insurance don't cover what it used to so I got half the drugs for twice the price. Reporter: To Roseanne's grandson who likes dressing like a girl. My grandson's nails are wet. I like your nail Polish, grandpa. That's drywall, son. Reporter: And center stage -- Every one of you wrapping yourselves up in the flag and clinging to your gun. That's such a stereotype. Where you going? I just realized we got kids in the house and I can't remember where we hid our gun. Reporter: The political divides within families following the 2016 election. How could you have voted for him? Roseanne -- He talked about job, Jackie. He said he'd shake things up. This might come as a shock but we almost lost our house. Have you looked at the news because now things are worse. Not on the real news. Oh, please. Reporter: At its peak the remere garnering 15 tweets per second. Mostly positive. One viewer writing, this conversation was needed. It's not a left or write thing. We the people agree to disagree. More people actually watched the show's premiere Tuesday night than the 1997 finale and all indications are that the show rest nailed with audiences across the country. It was highest rated, in fact, smack dab in the middle of America in Tulsa, Oklahoma, George. Thanks. Let's talk to Roseanne about it. She joins us on the phone. I know you're about to head to the airport. Thanks for taking the time this morning and congratulations on those huge, huge ratings the other night. It really sees like you struck a chord. Well, I sure am grateful to people for watching and liking it. It's very exciting. And obviously it excited the president as well. I guess he was excited about the ratings and you've been pretty outspoken in your support of him. How did the phone call go. It was pretty exciting, I'll tell you that much. They said, hole, please for the president of the United States of America and, you know, that was about the most exciting thing ever and it was, you know, just very sweet of him to congratulate us. What does he think about the show? Well, you know, we -- he -- we just kind of had a private conversation, but, you know, we talked about a lot of things and, you know, he's just happy for me. I've known him for many years and he's done a lot of nice things for me over the years and so it was just a friendly conversation about working and, you know, television and ratings. He does focus a lot on -- Oh, yeah, he really understands ratings and how they measure things and that's kind of been an interest of mine too for a long time but I'm just over the moon at the support of the "Roseanne" family, the Conners and people liking our show and all the cast, we all just, you know, celebrate together and just say, oh, the conner, you know, the Conners are back and we're all really happy. The Conners are back and the Conners are really digging in to these hot button issues that are affecting families all across America. Yeah, well, we like to -- we always like to be current and, you know, talk about the things that are happening in our country we always have on our show so we want to do it more. Do you think you guys are providing something that isn't being seen in movies, in television elsewhere? Yeah, I do. You know, the idea that people can agree to disagree is kind of missing from everything, but I think that's a conflict resolution and agreeing to disagree are important things that I like to feature and talk about and, you know, I haven't seen much of that anywhere, but that's what we need to do as a country is, you know, figure out what we don't like, talk to each other and, you know, discuss how we're going to get it changed or fixed. Well, you've had a great start. You think it's the start of something big again? Well, I really hope that it opens up, you know, civil conversation between people instead of mudslinging. I really do because I think we need to be more civilized than that. Well, Roseanne, congratulations again. Thanks for taking -- You guys are so nice. Thank you so much for calling me. Take care. You too, bye. It's like that phrase about family. We may not have it all together but together we have it all and what we've been saying and what she said and even the tweet that we showed before, yes, we'll disagree about things but you have to find those common ground. Find a way to talk about it. So many families in America have been dealing with that exact issue during this past election season. So it's awesome they're taking it on. Found a creative way, funny way and real way. Writing is sharp. It's just getting started.
