I liked it actually. Here's why.
What the movie is not.
It's definitely not an action packed suspense thriller or any thing of the sort by a long shot. So if that's your thing then you'll be disappointed.
What it is.
It's simply the life a young boy and his sister from a broken home. Both parents love them but were too young when they had children and made some poor life decisions. Really the movie goes through the highlights of literally a growing boy and sister with a single mom who see their dad a few times every week or so. It's actually very realistic in the sense that it's like any other person's life. They did a very good job at that.
What I like about it.
It has a subtle intellectual underpinning stressing this lack of fulfillment in your life. It shows how life decisions affect you later on in life. It gives an interesting perspective of a family that had to move several times through abusive situations. In the end they made it out OK, the single mother did a great job raising them and the father really grows up and becomes a father again. The children grow up and go to college and that's the end of the movie. What I like most about it is how it points out that you go through life, trying to achieve goals that are laid to you in society, acquire stuff and in the end it feels just as empty. I understand why that is but I think it's good that movie pointed it out. It is rated R though because of the language.
