Only a handful of cartoons have had the ability to tap into the cultural zeitgeist in the past 20-odd years, and “Family Guy” is one of them. Following the adventures (and misadventures) of schlubby, ignorant Peter, long-suffering Lois, and their buffoonish son Chris, awkward adolescent daughter Meg, and diabolical British-accented baby Stewie, along with their pretentious alcoholic dog Brian has made us laugh countless times, has given us an endless stream of quotes, and had made a star of its creator, Seth MacFarlane.
It’s hard to believe, but “Family Guy” has been on the air since its January 31, 1999 premiere, right after the Super Bowl. The show has certainly changed in plenty of ways since in the past 25(!) years – Stewie isn’t quite as hell-bent on murdering Lois; Lacey Chabert stopped voicing Meg after season one; several characters (or their voice actors) have died, including Mayor West, Mr. Weed, and Muriel Goldman; and Cleveland got his own short-lived sitcom – but much like The Simpsons, the show’s premise and emotional core has remained intact.
But like all long-running shows, certain seasons are widely regarded to be superior to others. These are the worst to best seasons of “Family Guy” according to its average audience score on Rotten Tomatoes, from season 1 through season 21. (For a more comprehensive list, click here for the best sitcoms of all time.)
21. Season 19
The most memorable aspect of “Family Guy” Season 19 is probably the arrival of Sam Elliott as Quahog’s new mayor, a rugged cowboy appropriately named Wild West. Other highlights of a rather uneventful season include Stewie saying his first word (that everyone can hear, at least), the F-word, in “Stewie’s First Word,” Peter becoming an Italian mob boss in “La Famiglia Guy,” and Stewie and Brian traveling to the future in Terminator-style adventure “PeTerminator.” It was also notable for being Mike Henry’s final season voicing Cleveland.

- Year: 2022-23
- Total Episodes: 20
- Audience Score: 55
Family Guy’s most recent season (as of 2023) featured the show’s 400th episode. The season premiere, “Oscars Guy,” spoofed “The Silence of the Lambs,” “American Beauty,” and “Forrest Gump,” and other (relative) standouts included “The Stewaway,” in which Stewie becomes obsessed with hide-and-seek and Lois falls off a cliff while trying to break Bonnie’s Instagram like record; “The Munchurian Candidate,” in which Lois brainwashes Peter into pleasuring her every time he hears the “Extra” theme song; and “The Candidate,” in which Stewis gets into local politics.

Season 11 featured the 200th episode, “Valentine’s Day in Quahog.” Standout episodes include “Brian’s Play,” in which Brian writes a hit play but becomes jealous when he finds out that a play Stewie wrote is better; “Roads to Vegas,” which changes up the usual Stewie/Brian “Road to” format by having a teleporter glitch create two different duos who have very different experiences in Vegas; and “Farmer Guy,” in which Peter buys a farm and becomes a meth dealer.
18. Season 12
- Year: 2013-14
- Total Episodes: 21
- Audience Score: 56
Season 12 was notable for a couple reasons: It saw the return of Cleveland after the cancellation of spinoff “The Cleveland Show” after four seasons, and it also famously saw the death of Brian in an arc that lasted several weeks and drew strongly negative reactions from viewers until it was revealed to only be temporary. Other standouts include “Into Harmony’s Way,” in which Peter and Quagmire form a folk band and “Vestigial Peter,” in which Peter gets a vestigial twin.

- Year: 2019-20
- Total Episodes: 20

Season 18 was “Family Guy’s” 20th anniversary, but it wasn’t an especially banner season.
