SEASON FINALE: NBC has ordered a second season of this charming summer series, so tonight’s doubleheader constitutes a season finale, not a series finale. That’s good news. Here’s more good news: Tonight’s installments include an episode in which series star Greg Poehler, as an accountant who had moved to Sweden to follow his heart, has to return to New York to help out a particularly demanding client – Amy Poehler. Also guest starring: Parks and Recreation co-star Aubrey Plaza.
