One of the very few movies that ever brought tears to my eyes

Rating: 9/10 (2 March 2014)

The only reason this is not a 10 is that I'll only give a 10 to a single movie in my life and I haven't found it yet. This got very close though.
It is worth watching because it goes down such a different path from what we're used to seeing from Hollywood. It's not bombastic, it's not about saving the world, the larger picture remains in the background. It's about what people become in the face of a terrible crisis and it lets you constantly revise your opinion of what you would have done in a situation like this.
This interpretation of Stephen King's novel conveys the message so believably, I wish all film adaptations were that good.
