Yes i saw this today and before anyone accuses me of spoiling,  pretty much all I say has been on all the Internet trailers in some form of another...

This movie stars John Cusack as the failed writer and failed father that is in essence the hero of the movie, Amanda Peet as his ex wife , Chiwetel Ejiofor as the scientist that discovers it all and Woody Harrelson as a crazy man out in the woods that trys to deliver the news to the public threw radio broadcast ( he has a mini station in his trailer kinda like the dude in Eight Legged Freaks).

The movie starts out in 2009 as a giant explosion on the surface of the sun. Adrian Helmsley (Chiwetel Ejiofor) visits a copper mine in India , supposedly one of the deepest mines/tunnels on the planet and discovers the earths core is heating at an exponential rate, causing the earths crust to eventually move and cause world wide havoc and destruction as well as causing a polar shift.

Jackson Curtis (John Cusack) finds out about the pending doom on a camping trip in Yellowstone where he encounters a government operation monitoring the volcanic status of Yellowstone.

Well to make a long story short he goes on a quest to save himself and his family and ultimately saves hundreds in addition to his own family.

Pros of this movie is the CGI special effects were astounding. The death and destruction was amazing and beautiful. The story was definitely a step up from "Day After Tomorrow" and "The Core"

The downside of the movie is it was all too predictable as well as very scientifically unsound. In the movie when Yellwstone blows all it does is throw a massive dust cloud when in reality the scientific fact is the sky will be blackened for months and all plant life will die off. There will be no survivasl period. it will be like a nuclear winter.

Well anyways i kinda expected it to be un-scientific and over the top but its still a great fun action movie.
