I just watched this movie,, this movie is great to bring awareness to CF, in my opinion the disease is not completely accurately depicted, there is not enough coughing or clearing of throat, a pair of CF people most definitely would not choose to take a walk uphill in the evening, and Stella would be sucking air hard, and beat red after her attempt to run the stairs. Not reality at all. But the information in the film was accurate, and it shines a light on an ugly disease.
Cheers!
