Kaitlyn Dever is entirely convincing as an Aussie! All the acting was amazing, especially Alycia Debnam-Carey and Tilda Cobham-Harvey. Very evocative show to me, being a cancer survivor myself, and I found the treatment scenes and those in which the characters agonized over whether to get conventional treatment or alternative therapies a little painful to recall. That anyone could fake cancer is deeply troubling, reprehensible actually.
