TNT provided a preview of its Dallas sequel during the season premieres of The Closer and Rizzoli & Isles. It’s impossible to judge any show on the basis of a one-plus heavily-edited minutes, but given the mix of Dallas stars old and new, Dallas redux looks…

purty tantalizin’. As previously reported, the new Dallas will feature Larry Hagman, Patrick Duffy, and Linda Gray in their original roles as well as two Desperate Housewives alums, Jesse Metcalf and Josh Henderson as the pivotal new generation.

The preview began with Duffy’s familiar regretful purr: “All those fights over Ewing Oil, and Southfork. We laid waste to everything in our path, J.R., and for what?” Bobby says. There was a shot of a liver-spotted hand, then a glimpse of some wildly overgrown white eyebrows — why, it was J.R. Ewing himself! Hagman sat in a chair in a darkened room, looking as though he was trying to turn Southfork into a set for The Godfather.

The preview jumped all over the place, of course, to keep you guessing just how much we’ll be seeing of which generation of protagonists. Duffy had most of the lines, and they were classic Bobby Ewing mewling — er, I mean, tragic soul-searching.

“I am sick to death of this family devouring itself over money!” said Bobby.

“No drilling on my ranch!” said Bobby to Henderson’s John Ross. They were standing on sacred Southfork ground.

It made me remember all over how much I liked Bobby, and Duffy’s impassioned line-readings.

The young ones looked scrappy. “Oil’s the past, John Ross,” said Metcalf’s Christopher, the adopted son of Bobby and Pam. “Couldn’t disagree more,” snaps John Ross. “You’ll never be a Ewing, Christopher!”

There were quick shots of Julie Gonzalo and Jordana Brewster looking romantic and stressed as the young women in John Ross and Christopher’s lives. And a brief close-up of Linda Gray’s Sue Ellen telling John Ross, “Think of me as your ally.”

The words “Money,” “Power,” and “Rivalry” blazed across the screen.

J.R. said, “Bobby was always a fool” and “I’m the one who belongs on Southfork. It’s mine, and only mine.”

“I don’t want them to be like us,” said Bobby, talking about the new-new-new Ewings.

Well, I do. The more the new young punks act like the ruthless barons of the 1980s hit, the better this series will be.

Dallas. Summer. 2012. I’ll sure give it a shot. As for why they’re rebooting Dallas? For every semi-pretty-decently-successful new version of Hawaii Five-O, there’s a (underrated in every sense) remake of The Fugitive. Let’s reconvene on this question after we all see the new-new-new Charlie’s Angels.
