A few hours past the halfway mark between Canada Day and the Fourth, go rent Blue State. A cute little charmer of an indie comedy that has a surprising bite to it, this is tale of two Americans trying to move to Canada in the wake of the 2004 presidential election. It paints with a pretty broad brush sometimes, but it does so in a pretty equal-opportunity way (the annoyingly earnest Kerry activist, the Limbaugh-listening military family president, and O, the Canadians...) and mostly in ways that still provide humor based on recognition and on truth. And if some of the movie is more about Canadian stereotypes of Americans and vice-versa than it really is about either place, well, border-crossings are sometimes like that.
To American expats in Canada, it's very funny.
