Johnny's comments:

Bad Girl is a teen thriller where troubled young girl Amy (Sara West) is forced to uproot to the country by her adopted parents Michelle and Peter (Felicity Price and Ben Winspear) and she is not too happy about it. They meet the neighbours, who suggest that Amy meets their lovely daughter Chloe (Samara Weaving) and a little later she arrives and offers her services to clean their house. Amy wants out and that night, spraypaints 'Sayonara' on the windows and waits for her city friends to pick her up, but they don't come. Amy has drunken herself into a stupor and ends up on the edge of bridge and almost falls when she is startled by Chloe, but Chloe helps her up. They form a friendship which involves Chloe helping Amy find her biological parents and stealing a car for a joyride, but soon their friendship becomes something more one night when they break into a motel room. Amy has a reason to stay, but there's something not quite right about Chloe and Amy is alerted to this when a detective comes to the door looking for a girl named Jessica who looks exactly like Chloe. She then finds out that the neighbour's girl isn't the Chloe she knows and confronts 'Chloe' about this and 'Chloe' takes Amy to a caravan where she's been squatting and shows her an ultrasound to prove that she is actually the daughter of Michelle and Peter. To which 'Chloe' bashes Amy and attempts to kill her and then usurp Amy as Michelle and Peter's child. Can Amy survive and save her adopted family before 'Chloe' causes more havoc?

OK but fairly stock standard stalker thriller despite playing slightly with convention by making the 'good girl' a troubled teen instead of someone who's perfect. Although a limited actress, Samara Weaving is quite good as the crazy bad girl play acting the angel, playing against type which works well for her here while Sara West is also good. Not bad and worth a look if you're into these types of movies (which I am), but not exactly essential either.
