Due to the large fanbase of the show that's splintered about a lot of things after the revival, Family Guy has this in spades:
- Due to a perception amongst some of the fanbase of declining quality since the show's resurrection in 2005, plenty of former fans prefer to believe the show ended with the third season – specifically either "Family Guy Viewer Mail #1" (final episode aired during the original run), "Road to Europe" (final episode produced) or "When You Wish Upon a Weinstein" (the Banned Episode; final pre-cancellation episode to be released). Basically, everything made after David Zuckerman left is ignored. However, exceptions are sometimes made for "Road to the Multiverse" (the Season 8 premiere) and sometimes for "Family Guy Presents: Laugh It Up, Fuzzball" (the Star Wars parody trilogy).
- Some fans will acknowledge the fifth season simply for the introduction of Brian's then-current girlfriend Jillian, but completely disregard everything after their breakup in "Movin' Out (Brian's Song)". Other fans consider the 5th season to be part of the show's prime.
- A lot of season 7 episodes – aside from "Road to Germany"note and "Ocean's Three and a Half"note – are ones that 1999-2002 era fans don't want to remember, whereas others consider it part of the show's prime, and the last good season.
- Many fans like to forget about the Season 8 episode "Brian Griffin's House of Payne", because of Stewie's massive head wound.
- Fans tend to ignore the Season 10 episode "Screams of Silence: The Story of Brenda Q." Now, Family Guy has done dramatic episodes before, like "Brian & Stewie", "Dog Gone", some parts of "Jerome is the Brand New Black", and the pre-cancellation episode "Brian Wallows and Peter's Swallows". But an episode playing domestic violence for drama coming from a show that isn't afraid to show women being beaten up, sexually harassed and assaulted, and mocked for their appearance and age, feels cheap and hypocritical.
- The Season 12 episode "Life of Brian" – in which Brian is very graphically run over by a car, is briefly dead for the next two episodes, and is replaced by new dog Vinny – ripped the show's already-tattered fanbase to shreds. Alternatively, some fans, primarily those who view Brian as The Scrappy, feel that Brian stayed dead after "Life of Brian" and Vinny stayed with the Griffin family for good.
- A lot of fans want to pretend that the whole Quagmire/Brian rivalry never happened. Considering the show's near-total abandonment of it, it appears most of the writers want to as well.
- Any of the show's attempts at a multi-episode arc in later seasons (such as Season 12's "Life of Brian", Season 16's "The D in Apartment 23" and Season 17's "Married... with Cancer"/"Dead Dog Walking") are more often than not ignored completely by most fans due to how bad they turn out with unsatisfying conclusions, often resulting in them being some of the worst episodes of their respective seasons.
