This is a response to the first comment. The annoying mucous dripping down her face and the productive cough is what a person living with cystic fibrosis deals with. This movie was very realistic when it came to the symptoms of CF. I am a survivor of CF due to a double lung transplant. Very health 32 year old woman who is very successful. As for the ending of the movie: It was quite strange and fortunately did not happen to me. Plus the way his wife got her lungs was also far fetched. In real life this does not happen. I was a bit confused as to why the movie ended the way it did. I think the movie could have been a bit more thought out dealing with reality. It was definitely far fetched but did keep me tuned in.
