I wouldn't begin to know how to categorize all of the above under a single rubric, let alone be able to say that this complex, variegated array of work somehow is qualitatively different from the complex, variegated array of work done by those south of the border. Of course, Canadians may write about different things, or take a different view on an issue than an American might. Of course not. But the only people who earnestly make this claim seem to be the ones who can't sell to well-paying markets. It's just a comfortable way of avoiding having to face up to their own artistic shortcomings.
Good stories are good stories.
