The human aspect could have taken precedence to excessive CGI The premise of the movie is clear. The world is coming to an end and secretly governments (only prominent countries, not all) plan for a modern 'Noah's ark' to place selected humans and some animals to continue the life cycle post apocalypse.
Good premise and special effects. But the over usage of destruction and constant chasing, constant escaping by the skin of the teeth take away the human element which could have been used to the movie's advantage.
Example the character Satnam, or the characters from Tibet, the US presidents personal side showing empathy and the protagonist's father etc so on were under utilized while focussing on excessive noise, destruction, death, collapsing buildings etc.
If only they toned up the human emotion / drama to the story and toned down on excessive CGI destruction, this would have been another Independence Day.
Ultimately it is human triumph against all odds.
