NEW YORK - Hit working-class sitcom "Roseanne" returned to US television screens Wednesday after a two-decade hiatus, winning generally positive reviews in a sharply polarized America with a title character who is now a pill-popping, Trump-voting grandma.

ABC aired the first two episodes of the award-winning show's 10th season - back for the first time in 21 years with actress Roseanne Barr in fine fettle as the eponymous blue-collar matriarch of the Conner clan.

Roseanne and husband Dan, played by John Goodman, are getting on in years, and are on a long roster of medication, which they share to save on cost.

"If you're not happy, I have no chance of being happy," quips Dan, handing the anti-depressants to Roseanne.

Daughter Darlene is back at home as an unemployed, single mom of a gender-fluid son and a bratty teenage girl. Son DJ is home from Syria, but with a wife still serving in the military overseas.

Daughter Becky, 43, is a widowed restaurant worker wanting to become a surrogate mom in exchange for $50,000, desperate to pay off credit cards, buy a car and put down a deposit on a home.

But it's the politics that's grabbed the press attention.

Depictions of working-class life are rare on US television, and Hollywood has largely ignored the half of the country that voted for Donald Trump.

Roseanne's sister Jackie (multiple Emmy winner Laurie Metcalf) sports a "Nasty Woman" T-shirt and pink hat of the type worn at women's marches against the Republican president's administration.

"What's up, deplorable?" she greets a feuding Roseanne, adopting Hillary Clinton's now infamous epithet for Trump voters.

"It's feisty and funny and a little sad. And like that old couch you can't throw out, it may just have a good year or two left in it," read a review in The New York Times.

The Washington Post called it an "engaging return to life" for the sitcom, whose first run went from 1988-1997, and which now is "sporting a fresh layer of relevance." - AP
