What a great role for Rachel Evan Woods ... of course the supporting actors do their jobs. But it is sort of her role ... and her movie overall. I did not know what to expect and the family she is in, is quite the interesting oddity! And her performance ... just awesome! You can tell from the start.
And it is not the easiest job. She has to walk quite the fine line. Her character is not really likeable! But she is quirky and weird ... and while she (but her parents even more so) does things that could be described as despicable ... we know it is her situation that motivates her. For that, she still seems to have a moral compass ... of sorts. Again very weird and crazy character.
She will clash with a "newcomer", which we can predict ... and also were this will lead to ... still the drama is well played and well acted (no pun intended).
