Three years before sailing on Titanic, Kate Winslet starred as one of the twisted teens in this fact-based drama about murderous schoolgirls in New Zealand. The fact that this story is based on truth makes it more, rather than less, creepy — as does Winslet’s intense-beyond-her-years performance. And another reason to watch: It's directed by Peter Jackson, before he went on to direct his Lord of the Rings cycle.
