For real, they look American, their impossibly fat dog looks American, the kid walks out drinking what looks to be a Bud Light, Cataract Grandma seems American enough, but something about this is just not American.
Maybe it's the 1985 boombox, that weirdly religious art work of what appears to be a boy scout with a Halo?, the way the girl wears her mom jeans, the kids tucked in t-shirt, or it could just be that they have a choreographed dance routine set to some euro-club song that involves a broad sword and a switch blade...I couldn't even offer up a guess as to where you could get either one of those things in the states...Everything about those two screams teens from Prague or Brussels, and yet I can't shake the fact that this is almost definitely set in America...
Wait a minute...I've got it...it's Canada, right? They're Canadians? American seeming enough but just a little off. Thank God. Mystery Solved.
