Take Shelter Reviews
the ending was pretty much uselss. I didn't hate it, but at that point the movie was a lost cause. and all the twist did was prove that he was right, it did not change anything else, or explain anything. it was just, "oh btw, he's not crazy" (1 viewing)
There is one thing this movie does great though, it's a fantastic indicator of whether you should trust someone's opinions on movies. If they like this, don't trust 'em.
