The movie I had watched week ago is about the calamity which is going to be faced by humankind (as claimed by the movie and some people). As I didn't do much research about the science behind the story, all I can say is that it is the end of the world, or more precisely, the changing of the earth into a new phase, an evolution... How true is that? Well I have no idea but I don't really want to give a damn since it doesn't matter anyway. It will be a good thing whether or not the world is meeting it's doom, since all things gonna come to an end no matter what.
Back to the movie, I can say that the idea about the end of the world is not really as exciting as it is, many movies use this idea and produce plots that are related to demise of everything. Basically 2012 is just using the same old idea to attract people to watch the movie, I bet it doesn't work that well so they decided to claim that the event will happen soon.. lol
Besides, the same old idea of Noah's Ark is used again, just like many other movies. Just wiki it if you don't know what is Noah's Ark, basically it is a ship that is used to save mankind and animal species... So the human in the movie has resolved to create a big metallic ship to accomodate most of the lifeform in it, which is disappointing as I was expecting something like a spaceship that let them travel to the space.
The plot is basically revolved around a random family who has tried uber hard to survive, to survive the earth quake, the volcano eruption, the catastrophe of collapsing building et cetera. Only one word can describe this, FAKE! Well, it is actually possible for them to survive those events (the movie proves it so), but what is the odd? The odd to survive one of the event is really so small that it is almost impossible, now that all the events have stacked together, the probability of it happening is even lower than for the end of the world to occurs. This can only happen in movie.
Conclusion is that, the movie isn't good at all, it is a waste of time to watch this movie. I would rather watch jurassic park than watching this. The only interesting thing to watch, in my opinion, is the destruction of the world, as how the building collapse et cetera. Besides, I would say that the message the movie is bringing to us is pretty REAL - that if we human don't do anything to protect the Earth, the end of humankind will be near.
So, take that as an educational movie.
