This movie is in my top 10 all time list. Michael Shannon gives one of the best performances i've ever seen as a man, Curtis, with a family history of schizophrenia who struggles with visions of an massive devestating storm. He uses all of his family's money to build a tornado shelter and his family must decide what to do with him. The movie is a fascinating study of mental illness and its effects on a family. TThere is not a single wasted line of dialog or wasted shot in the entire movie. This is a slow, character-driven movie that gradually ups the tension. If you thats not your bag, you probably wont enjoy the movie. If it is your bag, then you're in for a treat.
I would recommend that you see this movie, and if you do, do not read ANY spoilers about it at all. I do not want to spoil anything myself, but in reading some other reviews out there, it seems some people dont like certain key aspects of the movie. However, those people also completely missed the point, as thier reviews indicate they did understand, or really think about, what they saw. If you see this movie, pay very close attention to it. You will "get" the movie if you think about, not just WHAT Curtis sees in his visions, but WHY he sees them. If i said any more, i would be doing you a disservice. Needless to say, you need to see this movie. And you should probably see it with a number of your friends, because youre going to want to talk about it for hours afterwards.
If you have seen the movie, and want to talk about it, PM me.
