The message of this moving film trumps its over-reliance on sap, its overuse of cheese and its limited production values. What amounts to unrealistic character development is used to tell the true tale of a family and a young man struggling to battle cancer and struggling to comprehend God's role in their lives. The overall message of "finding truth" and illustrating how each of our lives can be a testament (or letter) itself to God is a great analogy. If viewed with an open mind and a hopeful heart, this movie will make you think and will move you to tears. I wish the creators of the film had taken a more realistic approach and used less pure sap to establish the story. I have a feeling that the "golly gee" or "Leave It To Beaver" level of writing will turn some people off. I know they wanted to pay tribute to a brave and courageous soul by portraying him as a pure saint on earth but the story would've packed even more punch had they chosen to go a more level route. Still, the message is strong and the story very moving.
