The last 25 years have been a golden era for television, delivering everything from gripping dramas like Breaking Bad to laugh-out-loud comedies. While many sitcoms have come and gone, only a select few have achieved perfection—shows with unforgettable characters, razor-sharp writing, and episodes that remain hilarious on repeat. Here are the eight most flawless sitcoms of the 21st century, ranked.
8. Happy Endings (2011–2013)
This cult favorite follows a tightly knit group of six friends in Chicago whose dynamic is thrown into chaos when Alex leaves Dave at the altar. The ensemble—Jane, Brad, Alex, Dave, Penny, and Max—navigates the awkward aftermath while trying to keep their friendship intact. Though it only lasted three seasons, Happy Endings is a masterclass in rapid-fire jokes and absurd humor. The characters' codependency and quirky rituals, like their invented holidays, make every episode a delight. It's a shame it ended so soon, but it remains a perfect gem.
7. 30 Rock (2006–2013)
Tina Fey's backstage comedy about a sketch show is a whirlwind of wit and satire. Liz Lemon, the harried head writer, clashes with network exec Jack Donaghy, played by Alec Baldwin, while managing the antics of Tracy Jordan and the rest of the TGS crew. 30 Rock is packed with clever one-liners, visual gags, and meta humor that skewers the entertainment industry. Its fast-paced jokes and iconic characters make it one of the smartest sitcoms ever made.
6. What We Do in the Shadows (2019–2024)
Based on the 2014 film, this mockumentary follows a group of vampires living in Staten Island. Nandor, Laszlo, Nadja, and Colin Robinson—an energy vampire who feeds by boring people—are hilariously inept at conquering the mortal world. Their human familiar, Guillermo, dreams of becoming a vampire while managing their chaotic lives. The show's creative lore and deadpan humor make it a standout, with each season delivering consistent laughs.
5. Abbott Elementary (2021–Present)
This mockumentary-style sitcom shines a light on the struggles of a Philadelphia public school. The dedicated teachers, led by the self-absorbed Principal Ava Coleman, work with limited resources but endless heart. Creator Quinta Brunson infuses the show with sharp social commentary and genuine warmth. Each season has brought fresh arcs, like the school's temporary move to an abandoned mall, proving the series has plenty of staying power.
4. New Girl (2011–2018)
After a breakup, Jess Day moves into a loft with three single men: Nick, Schmidt, and Winston. Zooey Deschanel's quirky optimism clashes with the guys' various neuroses, creating a hilarious dynamic. The show excels at building a found family, with standout performances from Max Greenfield as the preening Schmidt and Jake Johnson as the grumpy Nick. New Girl is a warm, funny series that only got better as it went along.
3. Veep (2012–2019)
Armando Iannucci's political satire follows Vice President Selina Meyer and her bumbling staff. Julia Louis-Dreyfus delivers a tour-de-force performance as the ambitious yet perpetually undermined Selina. The show's rapid-fire insults and cynical view of Washington make it brutally funny. Veep is a perfect comedy of errors, with every character being both incompetent and strangely endearing.
2. Arrested Development (2003–2019)
This pioneering single-camera comedy about the dysfunctional Bluth family is a masterwork of running gags and callbacks. Michael Bluth tries to keep his family together while they scheme and fail at every turn. The show's clever writing and layered jokes reward repeat viewing. Though its later seasons on Netflix divided fans, the original run is flawless, and the show's influence on modern comedy is undeniable.
1. It's Always Sunny in Philadelphia (2005–Present)
No sitcom has been more consistently hilarious than this dark comedy about a group of narcissistic friends who run a bar in Philly. The Gang—Charlie, Mac, Dennis, Dee, and Frank—are terrible people, but their schemes and delusions are endlessly entertaining. With over 16 seasons, the show has maintained its sharp edge and absurd humor. It's a perfect example of a sitcom that never jumped the shark, and it remains the gold standard for comedy.
These eight shows represent the best of what sitcoms can achieve. Whether you're in the mood for workplace satire, supernatural mockumentary, or pure chaos, these series deliver.
