It's basically about the end of the world in conjunction with the end of the Mayan calendar.
But it's so full of bad cliches it's embarassing.
SPOILER ALERT - below in grey on grey. Highlight the content below for the spoiler.
There on a boat and the 2 cabaret singers are singing a song that it's not the end of the world, before it is.
The Queen is see with her 2 corgy's going to this ark thing.
Their is a Russian billionairre guy who is as bad an actor as I have ever seen on tv. Look and see how wide open his mouth is when he talks, and it's reaallly slooowww, staart engine - but imagine it's arny speaking but 5 times slower and dumber.
And at the end when they are saved, nobody cheers, but then when 1 person is seen to be alive, then everybody is happy. Be like **** that [Poor language removed], i'm alive now, i'm happy now. Don't care about anyone else.
It's just poor.
Effects are well made, but the actual plot, acting, and realism of the characters is [Poor language removed]. Oh and there's even a black president because that's what America is like now. It's almost like they are afraid to cast a white man in that role.
What else? err, oh yeah this man who has had 2 flying lessons is saving his family from certain horrific death by navigating a minefield of falling debris, trains flying in the air, building dropping, fire, water, etc....it was like the Milennium Falcon and that asteroid field. 2 lessons, it's just unrealistic to the point of shameful.
Which is a shame because the effects are good, and the concept is a good one, just really really poorly executed.
