Neal Justin: Who will come out on top in 'Succession'?

You might assume that Ginny Morris watches "Succession" differently from the rest of us.

That's because she's a member of the Hubbard family, the closest thing Minnesota has to the fictional Roys, this generation's version of the Ewings of "Dallas" but with nastier put-downs.

But Morris, who runs the Hubbards' radio division, said the drama in the hit series, which ends its four-season run at 8 p.m. Sunday on HBO, has almost nothing in common with her real life.

"It's so unrelated to me," said Morris, who oversees stations in eight major markets. "I watch it like I watch a train wreck."

Morris said that she just had lunch with her brother Stan, CEO of the Reelz cable channel in New Mexico; brother Rob, who oversees KSTP-TV and other TV stations; and dad Stanley, the 90-year-old Hubbard Broadcasting kingpin who still comes to the St. Paul office every workday. If anyone stabbed another with a butter knife during dessert, she doesn't mention it.

She won't speculate on the idea that "Succession" takes its inspiration from the Murdochs, who seem poised for a power struggle of their own when 92-year-old Rupert Murdoch passes away.

"I'm sure there are families with high levels of dysfunction, but I'd like to think the shape the dysfunction takes on the show is completely fabricated," she said.

Before a winner emerges from the rubble, the show has flirted with farfetched twists. Earlier this month, we watched as the Roys' news channel called a presidential election on grounds thinner than a hanging chad. In last week's episode, Roman (Kieran Culkin), the clan's most sniveling son, threw himself into a horde of protesters, an unlikely move from someone who would cry over a paper cut.

Morris agrees that the show has occasionally ventured into the surreal. She grimaced at the Season 2 episode in which patriarch Logan Roy forced party guests to get on their knees and oink for sausages.

For a while, she thought Logan, played with Shakespearean gravitas by Brian Cox, had faked his own death to see how his kids would react.

"I thought maybe Logan had set them up. I guess that's the 'Dallas' fan in me," said Morris, referring to the moment in that '80s hit in which we discovered that Bobby Ewing wasn't dead after all.

Despite the show's often ridiculous nature, she has kept watching it. The performances and dialogue are just too rich to resist. One verbal argument between Shiv Roy (Sarah Snook) and semi-estranged husband Tom (Matthew Macfadyen) earlier this season could have been lifted from "Who's Afraid of Virginia Woolf?"
