I never cried of any movie but this movie makes me cry because it's not about the disability that stopped you. but it's the love that Sam gave to Lucy. if Lucy loses all of that love that his father provide for her it would dig a big hole and if Lucy grow up with that hole she's is trying to fill them. so this movie is trying to tell us never stop loving your beloved one, don't care about the obstacle they just need love. this movie reminded me of my dad when my dad got a heart attack and died.
