Firstly, I want to say that I wasn't too keen on the movie initially, because I thought the idea of an end of world scenario that happens so quickly without an instantaneous event (like alien invasion or meteor) would be hard to believe, and any plot would be eclipsed by the over-the-top total destruction on screen. Probably because of the low expectation, I thought the movie was barely entertaining.
For a 2.5 hour movie, the pace of the movie was pretty good. The movie was mainly carried by lots of localised disasters, like shattering earth, crumbling buildings, volcanic eruptions coupled with fireballs. While there was nothing being blown up, the actors did enough to deliver the urgency of the situation, even if the pseudo science wasn't so believable.
The almost non-stop destruction seemed pretty cool initially, but after the 20th close-shaves for the main characters, I found myself frowning at their dumb luck. As the car jumped over chasms after chasms, squeezed through gaps after gaps, the suspension of disbelief was completely destroyed. And I would later feel much less emotionally attached with the main characters, as the obstacles they faced from then on were nothing more than speed bumps on the way to definite survival.
The pseudo science was quite annoying, but I guess we can't fault them for trying. Providing a pseudo scientific reason behind the catastrophe was just being responsible. But couldn't get over the choice of the location where the human salvation project was built in the movie. Sure I know the was picked for the reclusiveness, jurisdiction of a superpower, anticipation rising sea levels. But seriously, if earthquakes are amplified around the fault lines, then it would be quite stupid to build the project in the mountains. After all, mountains are created because of pressure between tectonic plates.
All in all, it wasn't a bad movie, considering I went in with low expectation, but it wasn't great either.
