Setting aside the obvious questions of "how could it be THAT precise?" and "why did they take THAT path instead of just grabbing 'em?", an amazing what-if tale of knowing exactly when, where, and how many a series of horrible events would take. Just one piece of paper with a series of numbers, leading to a discovery of meaning that destroys one's philosophy of cause, effect, and probability.
The intensity is sustained, believable, and fresh. Great drama, great horror, thought-provoking. The previews I expect you have seen show imagery hinting at what I can reveal is an absolutely spectacular sequence of total devestation, winning this stage of the ongoing struggle of filmmakers to evoke the most mind-blowing depiction of the destruction of a popular location.
