I would go a bit further -- Greg Poehler's character is an insufferable asshole. He's cowardly, selfish, arrogant, thoughtless and whiny. Seriously, who could tolerate this douchebag for more than a couple of minutes? If the purpose of this show is to reinforce negative impressions of Americans held by non-Americans and fuel their hatred toward us, then it's doing it's job. After seeing 4 episodes of Welcome to Sweden, I hate Americans, too.
And ... Swedes? If this is how you really feel about Americans, please get over yourselves. You're no better.
