No, "The Brady Bunch in the White House," airing at 8 tonight on Channel 5, is not a political satire savaging the current administration. Rather, the Fox movie is actually a sequel to the sequel of "The Brady Bunch Movie," the 1995 theatrical release that delightfully mocked the sickly sweet early 1970s sitcom. Unfortunately the latest venture falls short of both that movie and the not-so-clever "A Very Brady Sequel," which came out a year later.

There's a good reason that "Brady Bunch in the White House" didn't make it to the big screen.

The latest effort is essentially a one-joke film that strings together enough one-liners and references to the original show to appeal to the most devoted Bradyphiles. The rest of us may get a few kicks from it -- it's hard not to chuckle at a Brady potato sack race on the lawn of the White House -- but the punch lines grow tiresome.

The premise is beyond silly, even considering that we are talking about "The Brady Bunch." The president of the United States selects Mike Brady (Gary Cole, reprising his role from the first two films) as his running mate after Brady uses a multimillion-dollar-winning lottery ticket, found by son Peter, to build a home for homeless architects and their families. The president, in the midst of a scandal, hopes that Mike's moral fortitude will reflect kindly on him.

But the president is eventually forced to resign and, just like that, the Afro-sporting, polyester-wearing Brady is sitting in the Oval Office.

The movie follows in the footsteps of its two theatrical predecessors by introducing plot lines and dialogue that parallel the original series. It does get tiring the third time around.

When Jan feels slighted by her parents, who are in a top secret meeting discussing a Mars space probe, she laments, "Martians, Martians, Martians!" -- a takeoff on her famous "Marcia, Marcia, Marcia!" line.

Peter's term paper on an asteroid collision with Earth gets mixed up with a NASA report, causing worldwide panic -- much like the episode when Mike accidentally took Jan's Yogi Bear poster to an important meeting instead of his blueprints.

You'll have to be up on your "Brady" trivia to get in on most of the jokes and, even if you are, that doesn't guarantee any laughs.

The movie's cheap look and sloppy use of news footage -- President Bush and former president Clinton seemingly appear unconvincingly at Brady's inauguration, a{grv} la "Forrest Gump" -- does not help the overall production either.

Cole's matter-of-fact suburban-dad delivery provides most of the movie's few high points. At one point he gently and amusingly scolds Cindy that "your tattling almost toppled my administration."

There's even a little political satire when wife Carol (Shelley Long, also reprising her role) announces an anti-pollution campaign that reflects the banality of real-life political slogans: "America's gotten messy. America should pick up its socks and clean up its room."

Spoken like a true first lady.

More dialogue like this would have made for a more watchable film. But the fact that the movie is mainly just a slew of bad "Brady Bunch" jokes leads to a recommendation: Vote no on "The Brady Bunch in the White House."

In a plot twist that is beyond silly, Mr. B (Gary Cole) becomes president and his wife (Shelley Long) first lady in "The Brady Bunch in the White House."
