The back-to-back-episodic premiere drew 18 million viewers and a 5.1 rating share in the critical 18-to-49-year-old demographic, according to CNN Money.

It is the highest-rated comedy on any network since 2014 and the premiere of CBS' "The big Bang Theory," according to ABC.

The show now, like before, centers on a blue-collar, working-class family in a fictional town in the Midwest, but now the Conner family is navigating the current tricky political landscape in the country as star Roseanne Barr, a real-life Donald Trump supporter, is a Trump supporter on the show, while her sister, Jackie, played by Laurie Metcalf, is a Hillary Clinton supporter. The show grapples with other relevant social issues like race and parenthood, too.

The original sit-com ran from 1988 until 1997, when it finished up its run to a much smaller audience than the one that tuned in for the series revival.
