I hope you’ve been watching the revival of “Dallas” this summer on TNT. If so, you’ve seen one of the best continuations of a TV show I’ve ever seen.

If you’ve been watching, you’ll want to tune in tonight at 9 on TNT for the season finale, “Revelations.”

The first season of Ewing family in-fighting – new but comfortingly familiar – climaxes tonight. So far this season we’ve seen the storyline move along two main paths: John Ross, the son of J.R. and Sue Ellen Ewing, was conniving to break into the oil business, even if it meant drilling on family homestead Southfork Ranch.

The plan caused conflicts not only with John Ross’ cousin, Christopher, and his father, Bobby, but also with J.R. Ewing himself, who wants to get his hands on Southfork.

The fate of both Southfork and Christopher’s alternative energy start-up has been at stake in a complicated scheme that involved a bunch of Venezualans. That’s all resolved nicely tonight.

The other main storyline depicted the romantic turmoil surrounding Christopher and his “good girl with a secret” wife Rebecca as well as John Ross and girlfriend Elena, daughter of the family’s longtime maid.

If you haven’t been watching and think that plot makes it sound like the older generation of Ewings – brothers J.R. and Bobby, J.R.’s ex Sue Ellen and Bobby’s second wife, Ann – get short shrift in the new series, that hasn’t been the case.

Most of the emotional high points – and the best lines of dialogue – of the new series have revolved around the older generation and that’s the case tonight too.

So here are some random, relatively spoiler-free observations about tonight’s last episode of the season:

If you saw the end of last week’s episode, you saw that Rebecca, trying to break free from the scheme involving her pretend “brother” Tommy, struggled with Tommy over a gun. There’s little surprise who turns up dead at the beginning of this episode.

Bobby, in the latest in a series of medical issues, ends up in the hospital. There’s a genuinely touching moment as J.R. urges a comatose Bobby to “wake up and fight … fight me.” If you’re not a little misty after this scene, you’re not a “Dallas” fan.

John Ross, trying to reform, teams with Christopher to found a new company, Ewing Energies. Best part: It’s located in the old Ewing Oil building (albeit gutted and unrecognizable from its dated 1980s glory. Probably for the best.). Even better: You know these guys are eventually going to be at each other’s throats.

One relationship ends, ostensibly, in tonight’s episode, while another begins, in good soap opera fashion.

For those of us who loved Mitch Pileggi as FBI boss Skinner on “The X-Files,” his role as a sleazy Dallas businessman here is a shock. But he gets what’s coming to him tonight.

Linda Gray, always a bright spot in the original series as Sue Ellen, has had an “okay” role in this series so far. She gets a few nice moments tonight, as does Brenda Strong as Ann, Bobby’s wife. It’ll be nice to see more for them next season.

The final scene between Bobby (Patrick Duffy, solid as ever here) and J.R. (Larry Hagman, worth his weight in black gold) is perfect. Just perfect.

There’s a nice twist – no spoilers here – in tonight’s episode but it’s telegraphed somewhat by the opening credits. Don’t pay too much attention to the names of the guest stars tonight or you might see it coming.

And you don’t want to see it coming.

The final scene of this season finale and the final line of dialogue are just right.

I can’t wait until next season.
