I don't think that Blood and Donuts feels like it's trying to be something it's not. It's definitely one of my favorite vampire movies just because of where it goes with the main character and his relationship with the women he falls in love with.
I've no doubt. I'm just airing out the Canadian perspective of how we usually refuse our own.
But this also might even be a generational thing. Rock is probably about 15 years or more younger than me and it's possible he didn't grow up with the national insecurity complex most people my age felt when it came to Canadian contributions to the arts. Maybe the youngers embrace Canada as a cultural force (as my generation snorts at them through so many shameful tears)
