Lovable rogues John and Jeremy are best pals as well as partners in a divorce-mediation service whose mantra is, "Don't blame each other -- the real enemy is the institution of marriage itself." But that institution is their guaranteed source of business and pleasure alike.

Who cares who's splitting up? Who's hitching up is what's important to "The Wedding Crashers," a k a Owen Wilson and Vince Vaughn, as they indulge their pastime of infiltrating a different marriage ceremony each weekend (in season), charming their way into some bridesmaid's romance-ready heart -- and, they hope, bed.

In this buddy-film farce, directed by David Dobkin, our boys can be Sean and Seamus at the O'Learys, Moish and Seymour at the Rosenbergs, or Luigi and Nunzio at the Garofalos -- whatever the ethnic circumstances require. After first targeting their pretty prey at the church or synagogue, they move in for the kill at the reception, charming everybody to death (balloon animals for the kids, dancing with the flower girl, dropping the fact that one is a "venture capitalist" and the other a charter member of Oprah's book club), all the while helping themselves generously to the food and booze.

Works like a charm every time -- until they bite off more nuptials and victuals than they can chew at the lavish wedding of the daughter of U.S. Treasury Secretary William Cleary (Christopher Walken). Seems he has two other daughters, winsome Claire (Rachel McAdams) and virginal Gloria (Isla Fisher), who fall for John (Wilson) and Jeremy (Vaughn), respectively.

John falls in love back (if that can be grammatically forgiven), which is a major violation of wedding-crasher rules. He also has to deal with Claire's hi-test (as in testosterone) boyfriend, Sack (Bradley Cooper). Jeremy has to deal with oversexed Gloria and with some unsolicited bondage and discipline from her brother.

We, like they, have to deal with Steve Faber's and Bob Fisher's silly screenplay, which has truly funny moments -- several of them with the immortal Henry Gibson as a preacher -- but also strained silliness and homophobic slapstick, with intermittent bursts of sincerity on the way to that inevitable schmaltzy music cue signaling those "lessons we have learned" at the end.

At which point, Will Ferrell's funereal variation on the theme almost -- but not quite -- redeems everything.

Overall, there's something raunchy for everyone here, and the R rating that goes with things like performing an under-the-table sex act. But there's less light madcap laughter than expected in the PG-13 summer comedy "Wedding Crashers" was originally supposed to be.

You'll have to judge for yourself -- but I just didn't find the two rogues all that lovable.
