4.3? Really? I voted an 8, actually. And I'm 100% agnostic.
I have to say I approached this film, expecting some laughable preachy "film" like "Left Behind" (either Cameron or Cage's version), and what I found was a film that simply put entertainment first, didn't shy off to be ambiguous and play the rapture as straight horror, which is how it would be perceived... the screenplay simply exposes a simple question to the audience: it doesn't matter if you believe or not, in the christian version of the Apocalypse... here's a world in which that version, happens, so, IF that happens, isn't the natural thing to actually say "hey, I was obviously wrong, and these guys were right all along?". It simply exposes that idea, while not forgetting to scare, give thrills, here and there, and not forgetting to develope the characters enough, to keep the action going and keeping you somewhat interested in their fate.
And it's not a "found footage" film. At all. There are some parts that are seen from the point of view of a videocamera o a smartphone. I liked it enough to buy it and I'm writting this while watching it, again, and liking it more than the first time around. And yes, I'm still agnostic and skeptical a God, if exists, would be so cruel.
Filmmaking is good, acting is not bad, some interesting ideas floating around - more philosophical than religious, most of the time, as there's a narrow line dividing both of them - and I certainly think this a rarity deserving of some praise, even if, of course is way far from being a masterpiece and budget limitations are evident.
