There's a synopsis and review of the spec script for Roland Emmerich's end of the world disaster movie 2012 that Sony bought before the writers' strike over at Latino Review. It is completely spoiler-filled so I'll only give the highlights here.
Since it's an Emmerich film and that pretty much guarantees it will be awful, I didn't mind reading the full thing.
Irwin Allen is best remembered for having pretty much invented the disaster movie genre with such films as The Poseidon Adventure and The Towering Inferno. To make sure he covered all the bases he went on to produce made-for-TV-movies with titles like Fire!, Flood! and Cave-In. :-)
Since aliens attacking the Earth to wipe out mankind and a weather-driven end of life on Earth weren't quite enough, Emmerich seems to want to carry on the spirit of Mr. Allen with a real disaster doozy: The end of the world in the year 2012, to coincide with the end of the Mayan calendar (or is it to coincide with the public interest in the year 2012 and cash in big? Nah...)
At least I'll give the script points for not blaming the end of the world on SUVs and cow methane, but instead on increased solar storm activity. Beyond that, it sounds like typical disaster movie pap, complete with cliched characters doing idiotic things, lots of "wow factor" in massive destruction, etc. From the sound of it, it seems like the Mayan connection is incidental and this is indeed nothing more than an attempt to cash in on the supposed upcoming event.
