There’s a new kid in Fox’s Sunday night animation lineup. And he speaks with an accent. “Bordertown” premiered this week on Fox. The show focuses on two families in the fictional town of Mexifornia: the Gonzalezes and the Gonzalez’ neighbors - and the patriarch of that family is Bud Buckwald, a border patrol agent. Hijinx, of course, ensues. The show is doofy and goofy, but it also pokes fun at complicated topics like assimilation and the foundering middle class.
