Good Disaster movies?

"The Day After Tomorrow"

"As nice as it is to encounter a blockbuster-sized movie dealing overtly with global warming, it would be nicer still if that film was directed by someone other than Roland Emmerich, the mayhem maven behind “10,000 B.C.,” “Godzilla” and “Independence Day.” Emmerich speeds up cataclysmic events leading to a second Ice Age that would occur at a more gradual rate in reality, in the interest of delivering spectacular CGI money shots of tornadoes decimating the Hollywood sign and an icicle-covered New York. It’s about as believable as aliens blowing up the White House"."The Happening"
Credibility rating: 1

Expecting credibility in a M. Night Shyamalan film is clearly misguided. Especially one nominated for four Razzie awards. Those who despised Shyamalan’s eco-thriller couldn’t stop rolling their eyes at a storyline that envisions toxin-emitting plants getting their revenge on the humans that have carelessly abused them. Needless to say, it’s not a phenomenon anyone should realistically worry about, so feel free to laugh when the film’s heroes start running from blades of grass."An Inconvenient Truth"
Credibility rating: 10

Just because this successful documentary focuses on a lengthy Power Point presentation doesn’t rule it out as a disaster movie. There’s surprising tension in former Vice President Al Gore’s lecture on devastation wrought by global warming, making the film more riveting than many CGI-heavy spectacles. Even more impressive is the array of concrete facts and statistics that Gore lays out. “An Inconvenient Truth” isn’t fantastical or science-fictional, which renders its plea for the human race to protect its Mother Earth all the more urgent.
