I was very surprised by how great this movie is. I saw Frailty for the first time a few days ago and I've watched it four times since.
I know some will be disturbed by the father's actions and that children are involved, until the end when you realize that he was doing the right thing.... In the context of the movie.
The kid actors did an amazing job. They were very believable. And Bill Paxton was terrific as both the father of the children and the director of this film.
I was also pleasantly surprised by Matthew McConaughy's low-key and disturbed performance. I've never seen him in a role like this before.
If you've never seen Frailty before, you should definitely check it out.
