Too little film for too great a cost - but it will be the 2nd best Blu Ray test disc to date after Avatar...

Rating: 5/10 (6 December 2009)

In fact I'm wondering if the Blu Ray will end up gold-plated for the amount of money thrown at the screen. I gave it half-marks because you can at least see where that cash went just by watching it.
The main spoiler, is that there is no plot to spoil. The upside is you get 40 minutes of general setup but only for 4-6 characters, then it's a destruction-fuelled roller-coaster ride to the end. The problem is, we've had September 11th for real, the telephoning and saying goodbye to loved ones and total lack of hope happened for real eight years back so it's overtly cynical to manipulate the audience that way - 2012's emotional blackmail makes Spielberg's trademark sentimentality look ice cold.
Also I can see the general subtext here, the most featured deaths along the way happen to people who've had affairs or let down their family in some way without any attempt to fix it, though there is the standard Hollywood "Redemption by Act III" for one unpleasant character in the party of survivors. The pace of the destruction lets you forget that you're getting variations on the same death scenes, but the whole end feels tacked on and boring.
So if you have Blu-Ray player and a flat TV of 37inches and above...you could probably pass on 2012 bar maybe a rental.
