Query: POWER-FILLED MOVIE!

My daughter is in the end stage of the terrible disease of cystic fibrosis. She saw THE POWER OF TWO at a special showing and reception attended by one of the twins. Their story gave her and our son-in-law much reason for optimism in her own case, while also providing much useful and inspiring information. It's an excellent documentary and has helped me to better understand what my daughter will be experiencing upon being accepted as a double-lung transplant recipient.
