“[Del Rosario] is outstanding as the 200-year-old trapped in a 12-year-old girl’s body, combining impressive athleticism with a child-like wonder, giving this bloodthirsty killer a sympathetic edge. She worries about Oskar’s bruises from bullying and tries to encourage him to fight back. For her part, she leaps viciously on her victims, and later, gently snuggles up to her new “boyfriend” with an innocence that is shockingly at odds with what we know she is capable of.” — Terry Byrne (Boston Globe)
