Sally Field as Nora Walker

Weirdly enough, the Walkers are one of the more realistic families on television today.

The "Brothers & Sisters" clan is loud, boisterous, intrusive, argumentative, loving, opinionated, obnoxious, sweet and, ultimately, care deeply about one another.

Just like families in real life.

Most of us don't have as much money as the Walkers. Most of us don't have a U.S. senator/presidential hopeful in the family. Most of us, upon the death of the family patriarch, don't discover that he had a long-term mistress and we have a half-sister that resulted from that relationship.

(Maybe the Walkers don't have a half-sister, either.)

"Brothers & Sisters" (Sunday, 9 p.m., ABC/Ch. 4) is a big soap opera. Not that that's a bad thing. There are a lot of characters with a lot of things going on, and that keeps things interesting.

But because these are characters who love one another — even when they're fighting — "Brothers & Sisters" is as addictive and entertaining as anything on TV.

The show is at its best when the Walkers are gathered together and things start to get a little crazy. And that's exactly what happens in the show's first post-writers'-strike episode when Nora (Sally Field) is confronted by her grown children at Rebecca's (Emily VanCamp) birthday party.

(Nora has accepted Isaac's invitation to move from California to Washington, D.C., to be with him.)

"Is this normal?" asks David (Ken Olin).

"I don't know. I'm new here," replies Graham (Steven Weber).

Yeah, it's normal.

After a four-minute scene that opens the episode, the "Brothers & Sisters" narrative jumps ahead three months. Not to give too much away, but there's a resolution of sorts to Robert's (Rob Lowe) run for the White House. (Or is there?)

Sarah (Rachel Griffiths) is indeed involved with Graham. And there are some business dealings involved with that.

The question of who Rebecca's biological father really is gets raised again, and there's a resolution in sight. (Or is there?)

There might even be a resolution to the Nora-and-Isaac storyline. (Or is there?)

But the family will still be fussin' and feudin' and lovin' — and we wouldn't want it any other way.

THERE'S GREAT NEWS for "Battlestar Galactica" fans. Or maybe it's not so great.

"BG" executive producer Ronald D. Moore — the man who transformed the cheesy '70s series into the great "Galactica" we have today — wrote a two-hour TV movie/pilot for "Virtuality." It's about a starship that leaves Earth on a 10-year exploratory mission.

The ship is equipped with a virtual-reality system (can you say "holodeck," Trekkers?) that allows the crew to assume different identities and go on various adventures. But — gasp! — there's a flaw in the system.

But — and it's a big but — "Virtuality" has been sold to Fox. And Fox doesn't have a great track record when it comes to being patient with shows. And it has an even worse record of patience with science fiction-y shows.

Can you say "Firefly," sci-fi fans?
