This isn't my favorite episode of Parks and Recreation, but it's not bad. There has been many changes to earlier seasons, so I can imagine conformist fans hate it, but let's be honest - when a sitcom story evolves to a point where main characters are getting pregrant, it has already been pretty boring and repeatitive for a while. Jumping three years is actually a clever way of avoiding forced baby humor many series, such as Friends or How I Met Your Mother, had.
But what makes this episode special is the fact that it has the most random cameo role ever. Werner Herzog, the director of Aquirre and Fitzcarraldo sells an old house to Andy and April. Most watchers won't notice this, but for the truest film buffs this is something else.
