This movie is family friendly but more suited for teens than for young children, due to the subject content. THIS MOVIE WILL MAKE YOU CRY! You can read the online plugged review here, but be careful because there's a spoiler! Read slow so you will be sure not to read about the ending.
I think the review explains the movie so much better than I can so please take the time to read more about it. Here's the trailor to the movie if you'd like to take a peek.
