The concept of this film is LAUGHABLE !!
I am shocked to know that this movie is directed by Danny Boyle.
First of all, our sun is nowhere near it's death, it still has a couple of billion years to exhaust it's nuclear power, this won't be happening in the 2050's and the idea of it is just absurd and uneducated.
Second of all, how can they compare the sun's unimaginable nuclear fusion to ANY KIND OF MAN-MADE BOMBS ??? are they really that naive to think that a quadrillion gazzilion bombs can actually affect or even reach the sun's surface?? people should read and learn about physics before coming up with such horrendous ideas.
Not to mention that when the sun is about to die it only gets bigger and bigger devouring Earth entirely... therefore the temperature here on Earth before it's wiped out by the sun would be hotter not colder as they suggest in this film.
I'm not going to get into the third act and how UNBEARABLE and PAINFUL it was to watch.
Boyle should stay away from Sci-Fi films.
