Just taken DS to see it and pleasantly surprised. It's about sisters, who save themselves and each other; the two main male characters are respectively an abusive liar and a well-meaning berk. Definite Bechdel pass, as well: the sisters talk to each other about their lives and their relationship with each other.
OK they both have impossibly tiny waists and big dumb eyes, but the film ends with the older sister settling into happy single queendom, and even though she Does Bad Things earlier on it's presented very much as Not Her Fault. I even managed to discuss in a whisper with DS how silly her parents were...
