The show could have been so much more, but Greg's awful acting, horribly played-out sad-sack role could have been given so much more depth if it were played by another actor. Any other actor.
The show does play hard on the cultural discontinuities between life in the US and life in Sweden, striking up *every single* possible stereotype (and I've got no problem with that), to the exclusion of other location-agnostic jokes that might be a good fit for that specific situation. The show's writers obviously suffer from a strong lack of creativity or have been specifically told to keep the topic on Sweden. All the time. Yawn.
What would really help take this show into a second season (or at least to the end of this season before being canceled) is if the writers added a little more depth to his wife's character and showed us more of the parents (who seem like engaging actors taking on roles that beg more exploration). I can honestly say that all 5 points that I've awarded this show go firmly to the actors who play the family of Josephine Bornebusch. Hopefully one of the Poehlers is reading this.
