Family Guy Season 20 Celebrating two decades, Season 20 includes several callbacks to classic episodes and gags. Stewie and Brian take a nostalgic trip through their past adventures. Peter continues his nonsensical jobs, from being a trivia champion to leading a street gang. The humor ranges from crude to sentimental, with a few episodes leaning into quiet reflection. One standout episode revisits Stewie’s birth with an alternate perspective. The animation receives minor stylistic updates. Meg and Chris play smaller roles, but the family dynamic remains strong. The season acknowledges its history while poking fun at the idea of “still going.”
