As it is, it's worth watching for its sheer imaginative exuberance, unabashed passion, and brash confidence. Let's just hope that with his next movie Anderson takes the advice of a good script editor.

Not that he needs any help with the film's first 15 minutes, which are as compressed and organic as the rest of the film is loosely wrapped and overwrought. A tongue-in-cheek prologue in the mode of Unsolved Mysteries presents three examples of how invented truth is stranger than fiction, a trio of "historical" cases of coincidence and poetic injustice illustrating the truism that fate and synchronicity often add up to more -- and less -- than meets the eye. A cut is made to a gorgeous, computer-generated magnolia blossom unfolding in intricate detail to the tune of Aimee Mann singing Nilsson's "One," and that carries over to the breathless, tracking introduction of the film's major characters and storylines, an overture so dense and fluid that if it were sustained much longer, exhilaration would give way to exhaustion.

Mercifully, and perhaps unfortunately, the pace slows and the interbraided story motifs are unraveled. It turns out that Anderson tends to mistake redundancy for depth. Most films would be satisfied with just one abusive father dying of cancer seeking reconciliation with an estranged child; this one's got two. There's Earl Partridge (Jason Robards, chewing the scenery as well as his oxygen mask), a TV executive on his death bed attended by his neurotic trophy wife, Linda (a paler, weepier Julianne Moore), and by his compassionate male nurse, Phil (Philip Seymour Hoffman in a rare bland role). Earl's last wish is to get back in touch with his estranged son, Frank (Tom Cruise, back to the id-channeling of Born on the Fourth of July after the repression of Eyes Wide Shut), a male-empowerment guru whose motto is "Respect the cock! Tame the cunt!"

Sick bad dad #2 is Larry Gator (Philip Baker Hall), the crapulous host of the kiddie quiz show What Kids Know. He's trying to get back together with his estranged daughter, Claudia (Melora Walters in a cunning, fragile performance), who's a junkie. Meanwhile, LAPD loser Jim Kurring (John C. Reilly), a cop who passes the lonely cruising hours (riding shotgun with him is a shotgun) pretending he's on Cops, has responded to a complaint at Claudia's apartment and in between reciting platitudes to her thinks he's fallen in love.

Then there's not one but two abused child prodigies. The older, Donnie (William H. Macy), has traded in his '60s quiz-show fame for a job at an electronics outlet and a desire to get braces in order to be like the bartender he has a crush on. The younger, Stanley (Jeremy Blackman), dazzles the audience of What Kids Know by singing lyrics from Carmen in French but still can't get love from his father (who is not dying of cancer) or a bathroom break from the show's draconian producers.

So what of the black woman with the dead man in her closet, or the prophetically rapping kid who steals Kurring's gun? Intriguing loose ends, they don't get tied up in Anderson's day-in-the-lives fugal structure, which culminates in too many teary climaxes. One, in which Robards whines for 10 minutes, is insufferable; another, in which various members of the cast improbably pick up, à la The Umbrellas of Cherbourg, the refrain of Aimee Mann's haunting "Wise Up," is both hilarious and touching. In general, though, the ambitious counterpointing of eight of her songs with the narrative doesn't quite pay off.

What does pay off is a turn in the weather that is both absurdly unexpected and, given the odd Biblical reference spotted on marquees and elsewhere (not to mention the film's heavy debt to Robert Altman's Short Cuts), surprisingly apt. This device too suffers from overkill, but it's a welcome relief. After hanging as dense and heavy as the scent of the title flower for what seems several lifetimes, Magnolia blooms into its apocalyptic finale not a moment too soon.
