Family Guy Season 4 After a two-year cancellation, Family Guy returns with a bold, confident season. The animation improves noticeably, and the writing leans into riskier jokes. Stewie and Brian emerge as the show’s emotional and comedic core, often carrying full episodes. Peter’s absurd logic and behavior escalate, pushing the boundaries of sitcom tropes. The season includes fan-favorite episodes like “Petarded” and “PTV.” Cutaway gags increase in frequency and absurdity. The show also begins to mock itself, including jokes about its own cancellation. Season 4 reestablishes Family Guy as a major player in adult animation.
