So this little boy has cancer... the mom and brother are doing all they can to hold it together to be strong for the little guy...
And what does he do?
Manages to help them... and from the sounds of it... help pretty much the whole community while he's at it.
The movie is based on a true story (and that always gets me in the tender-sensitive-mom-cries-at-everything kind of way).
A little boy, some letters to God, and a postman willing to help make a difference. I'd call that a recipe for a successful family film. (And did I mention the trailer will make you cry? Oh. I did. Well you've been warned... AGAIN.)
