Well "WOW" would be the first thing I would say about this movie, it was so not what I thought it was! It's certainly interesting and the Hubster knew exactly what it was trying to depict by the end (Biblical connection), and I'll say nothing more so as not to ruin it.I'm a fan of Nicolas Cage, most of his movies are entertaining and often make you think, and this is another one of those. It wasn't at all what I expected and got pretty spooky in parts and I don't do 'spooky'!! But I made it through, although I did have to go around and close all the curtains to stop me totally freaking out.Followers or students of prophecy/astronomy will probably have a field day with this film. It certainly made me think and maybe global warming is already out of our hands, this will make you wonder. I'd recommend it but watch out for the 'jumpy' bits!
