McConaughey in a horror/thriller? I had to see this. I was pleasantly surprised.The plot is told in flashback mode, and it concerns an otherwise normal and happy family of three going through a very bizarre predicament. I can't say much more without spoiling the whole movie, sorry. Just know that if you decide to watch it, you'll be, in the very least, surprised.All the main players are very good. Bill Paxton did a great job directing those kids, and his acting is awesome. McConaughey's acting is solid throughout and fits the bill perfectly.This movie challenges you to think. Is Dad crazy? Is there a God? Do Demons exist? How far would you go to right a wrong. And what is "right" anyway? I'm still thinking.And thus I recommend "Frailty". 7/10 and this is one of those movies that deserves and rewards a second, or even third viewing.
