This long-running animated comedy focuses on the eponymous family in the town of Springfield in an unnamed U.S. state. The head of the Simpson family, Homer, is not a typical family man. A nuclear-plant employee, he does his best to lead his family but often finds that they are leading him. The family includes loving, blue-haired matriarch Marge, troublemaking son Bart, overachieving daughter Lisa and baby Maggie. Other Springfield residents include the family's religious neighbor, Ned Flanders, family physician Dr. Hibbert, Moe the bartender and police chief Clancy Wiggum.

"Homer the Whopper" didn't try anything new (could it have?), but I had fun with it all the same. Go to Full Review Robert Canning IGN Oct 31, 2017

The lackluster episodes may have felt tired, but even they could supply a genius bit here and there. Go to Full Review Josh Kurp Uproxx Oct 26, 2017

stephenpaul C @ash20261234567890 Sep 13, 2026 23 funny Fox episodes. See more diogo13 T @Tua_mera Jul 11, 2026 A regular season that flirts heavily with the pop culture and technology trends of the 2010s. It doesn't try to reinvent the wheel and stays far away from the acidity of the past, but it manages to entertain and keep the show at a comfortable average level as a good pastime. See more Stephen C @bob25009 Jan 3, 2026 23 funny episodes, including "Homer the whopper." See more TheMovieSearch R @TheMovieSearch Dec 12, 2025 Season 21 of The Simpsons continues the long-running series with its signature humor, satire, and cultural references, but it’s clear the show is past its peak. While the series still delivers clever moments and occasional laugh-out-loud scenes, the storytelling often feels uneven, with some episodes lacking the sharpness and emotional resonance of earlier seasons. The animation remains bright and colorful, maintaining the iconic Springfield charm, though certain plots feel recycled or predictable. Voice acting is consistently strong, with the main cast delivering their characters flawlessly, but guest appearances vary in quality. Some episodes are genuinely entertaining, showcasing clever satire and social commentary, yet others drag or rely too heavily on pop culture jokes. Overall, Season 21 has its moments of fun and nostalgia, but it also highlights the challenges of keeping a decades-old series fresh and engaging for both longtime fans and newer viewers.
