Because ever single person in this story is as much a superhero as any character I've ever seen on-screen before. Whether it's Sam, his parents, all of the children we meet, their parents; there's a fervent focus and persistence to living life to the fullest and finding lemonade in the sourest of lemons life has to offer, moving you in inexplicable ways. Scott and Leslie, the parents of Sam, are truly saints and the latter's dedication to finding a cure is simply breathtaking. Above all, it really just infuriates you how something so cruel like progeria could ever exist.
I wish I had the opportunity to meet Sam, who sadly passed away a year after the film's release. He seemed like a genuinely awesome person who just wanted to enjoy life and all of its simplest pleasures. He inspires me to want to live everyday to the fullest and I hope anyone who hasn't seen this documentary does, if just to get to know this wonderful human being.
