Greg Poehler, as an American willingly transplanted to Sweden to experience the land and lifestyle of his Swedish girlfriend, is very droll and funny here – and Josephine Bornebusch, playing the girlfriend, is one of the most pleasant surprises of the summer TV season.

And in tonight’s episode, even in this remote location, Welcome to Sweden finds room for another guest star: this week, it’s Aubrey Plaza, from Parks and Recreation.
