A veritable master of disaster, Emmerich already has made lots of stuff blow up real good (invading aliens zapping the White House in "Independence Day") and lots of other stuff get water-logged real good (remember the Russian tanker sailing through midtown Manhattan in "The Day After Tomorrow"?) and even more stuff gets flash-frozen, blasted by tornadoes and otherwise assaulted by won't-get-fooled-again Mother Nature.

If that's your idea of fun, fun, fun, then you'll absolutely adore "2012," which puts everyone on Earth on a countdown to oblivion.

This being an Emmerich extravaganza, you know oblivion will hit -- in multiple spectacular ways.

You also know that billions of faceless people will die, but a few plucky souls will prove the resilience of the human spirit by surviving (just barely) relentless multiple special-effects assaults.

If you're not into those multiple special-effects assaults, however, "2012" offers few other diversions -- especially because there's nothing in this movie we haven't seen many times before.

Oh, I don't mean the computer-generated effects aren't impressive, in their coldly efficient way.

But now that we know computer effects can conjure pretty much anything and everything, that makes the spectacle of mass destruction just another ho-hum digital workout for all but the most enthusiastic mayhem junkies.

Even Las Vegas' inevitable devastation (what, you thought Vegas wouldn't be invited to the end-of-the-world party?) seems anticlimactic in the face of so much over-the-top excess.

Maybe that's because disaster movies live -- or die -- on the strength of the few characters who do manage to survive multiple cataclysms. And in "2012," they're not exactly the most compelling bunch.

In our Everyman corner, we have failed writer Jackson Curtis (John Cusack, maverick-y as ever), who's been reduced to working as a chauffeur since his futuristic novel tanked and his neglected wife, Kate (a wan Amanda Peet), divorced him. She's since taken up with Gordon (Tom McCarthy, better known -- for good reason -- as the director of "The Visitor" and "The Station Agent"), a plastic surgeon who's been a much better parent than Jackson to his kids (Liam James, Morgan Lily).

But Jackson's determined to make up for his failings -- by taking the kids on a camping trip to Yellowstone National Park, destined to become the world's doomsday hot spot.

Meanwhile, on the other side of the world, "2012's" resident Noble Scientist, Dr. Adrian Helmsley (too-good-for-this-movie Chiwetel Ejiofor) and an equally worthy Indian colleague (Jimi Mistry) discover the awful truth: Massive solar flares are overheating the Earth's core and will inevitably trigger unprecedented disasters, from earthquakes to volcanoes to tsunamis so gigantic Mount Everest could become a beach resort.

Naturally, global leaders -- led by the U.S. president (a dignified Danny Glover) -- prepare for the worst. But arrogant White House adviser Carl Anheuser (Oliver Platt, who could use a moustache to twirl) and his fellow greedheads aren't about to let altruism interfere with survival. Unless, of course, our heroic Everyman and Noble Scientist manage to thwart his nefarious schemes first.

No one expects a movie such as "2012" to explore the anguish of the human condition in the face of global disaster. (If you're looking for that, try the movie version of Cormac McCarthy's Pulitzer Prize-winning "The Road," which opens Thanksgiving Eve.)

But is there some international edict requiring "2012" to be so ridiculously overwrought?

Emmerich scrupulously follows the Disaster Movie playbook that's been in force since the genre's '70s heyday, when such bloated all-star entertainments as "The Towering Inferno" and "The Poseidon Adventure" distracted audiences from Watergate, runaway inflation, the energy crisis and other feel-bad issues.

These days, we're at least as deep in feel-bad doo-doo, but "2012" isn't going to make you feel any better if you care even remotely about such vital cinematic elements as a credible story line and sympathetic characters.

The screenplay (credited to Emmerich and his "10,000 B.C." co-writer, Harald Kloser, who also contributed to "2012's" bombastic musical score) piles up so many credibility-defying situations -- inevitably accompanied by suitably ludicrous dialogue -- that you feel for the poor performers trying to refresh material so far past its sell-by date. (Some of them, wisely, don't even try -- notably Woody Harrelson, having a hammy blast as a wild-eyed radio prophet who's an expert on the impending apocalypse.)

Mostly, though, we await the arrival of the latest volcanic fireball or cascading tsunami -- to take out the most annoying characters. With so many worthy candidates, it's tough to determine who deserves it most, but let's hope at least one manages to find Emmerich.
