The science is terrible, the CGI is awesome.

Rating: 8/10 (18 November 2009)

From magical morphing neutrinos that can interact with matter to disaster immune planes that can't gain altitude, in the science category this movie gets a solid F. The writers couldn't grasp a passing understanding of poles, faults, geography, how fast buildings fall, volcanic eruption, altitude, or how much water is actually on earth. The character development is terrible and rife with stereotypes, and humanity in the movie would have been better off without the main characters ever existing as they nearly wiped out 1/3rd of humanity. So rack up another F in the character department.
However, I still gave it an 8 because of the CGI and hilarity. Most of the flaws are in the name of making the effects that much cooler, and the camera's perspective in many of the shots was excellent. Despite the scientific inaccuracies, where else will you see a limo drive through a slowly falling building, St. Peter's Basilica (with pope) squish a bunch of worshipers, a nuclear volcano's bomb obliterate a crazy radio host, or an aircraft carrier smush the US Capitol? The flaws make this movie very funny; the stereotypical billionaire, data that can predict down to the second yet neglect an entire continent, the ships built in China (like everything else), and the ex husband catching a break when the new husband is ground into hamburger.
That being said, this movie is better suited to one of those roller coaster simulators than an actual movie.
