If nothing else, this movie succeeds at evoking a very specific atmosphere: you can almost feel the damp, northeast chill coming off the lake. And the girls act like northeast girls! Sure, Kate Bosworth's crazy eyes can be a tad disconcerting, and I'm always vaguely afraid of being swallowed whole by Lake Bell, but overall, it's definitely a film that positions the viewer on the outside looking in.
The action is set on an odd piece of geography: an island that is apparently much bigger once you're on it, than it appears to be from the shore.
The DVD-extra interviews w/ the cast and crew actually make the characters significantly more despicable, when their ignorant motivations are spelled out.
It's a testament to society's preconceptions about the hierarchy of atrocity that an attempted rape of a fickle seductress is considered more egregious than the resulting murder of the horny young cuck. *sigh* Yay ... grrrl power?
