And the public gets what the public wants.
Roland Emmerich was armed with a $200 million budget, and this is what it produced. It's an easy film to dislike from an intellectual level, artistically as well, while the science fiction boffins no doubt had kittens where the science was concerned. It's also easily one hour too long in length, and come the second half of the marathon it starts to sag. There's only so many times you can watch your lead protagonists escape crumbling carnage - via various modes of transport - before the fun factor begins to wane. However.
The carnage effects are grade "A" stuff, eye popping and ear splintering, Emmerich is a master at this sort of thing, and with a likable cast comfortably chewing through the safe disaster film making screenplay, it's a very decent popcorn blockbuster. It also isn't afraid to explore some dark moments, all of which - while not all being a surprise - strike strong emotional chords. It knows its disaster movie roots and is happy to tug on them.
2012 made a $500 million profit, that's a figure not to be ignored. The blockbuster movie loving public lapped it up, they often love this stuff, they just want to see the world exploding and chases and crashes and humans imploding or being heroic. If you have to strip it bare on any sort of cerebral level, then of course it's naked. But fully clothed, attired purely in modern film popcorn clobber, then it's grand dramatic and exciting fun. And this even as you have to massage your buttocks at the two hour mark. 7/10
