Eighteen seasons in, the Gang’s newest enemy is non-alcoholic beer. This feels correct. Dennis, Mac, Charlie, Dee, and Frank have survived scams, lawsuits, kidnappings, cultish thinking, exploding relationships, and their own astonishing judgment, so modern drinking habits were bound to become an existential threat sooner or later.
It’s Always Sunny in Philadelphia enters Season 18 after 21 years on television with its basic comic machinery intact. Paddy’s Pub remains headquarters for five people who can turn a minor inconvenience into a municipal emergency before lunch. Dennis Reynolds (Glenn Howerton), Dee Reynolds (Kaitlin Olson), Mac (Rob Mac), Charlie Kelly (Charlie Day), and Frank Reynolds (Danny DeVito) continue to learn essentially nothing, which has become one of television’s longest-running commitments to character consistency.
Season 17 gave the modern era of the series a jolt through stronger continuity, the Abbott Elementary crossover, and Frank’s Golden Bachelor romance. Season 18 carries some of that material forward before settling into a familiar weekly rhythm of schemes and arguments.
The difference now is age. These people once looked like young adults refusing to mature. They now look like adults discovering that society matured without them. Bad news for society.
Grief, Corpses, and Bad Ideas
The first two episodes give Season 18 unusual narrative continuity, picking up several threads from the previous year while confronting the death of Bonnie Kelly following the passing of Lynne Marie Stewart. Naturally, the Gang responds to mortality with financial planning and corpse-related chaos.
“Frank Marries a Corpse” sets the tone immediately. Frank’s relationship with the woman he chose during his Golden Bachelor adventure takes a horrifying turn, while Charlie deals with his mother’s death through increasingly misguided attempts to honor her. The episode has real emotional material sitting underneath the obscenity, especially whenever Charlie Day lets Charlie’s usual frantic rhythm slow long enough for the loss to register.

Day’s performance has always been funniest when Charlie’s strange internal logic feels completely coherent to Charlie. Grief complicates that. His plans grow ridiculous, yet the impulse driving them is unusually recognizable.
The episode occasionally tries to carry too much at once. Frank’s relationship, Bonnie’s death, funeral behavior, and everyone else’s competing schemes pile into the same twenty-something minutes. The chaos is funny, though Charlie’s material occasionally feels like it needs another beat before somebody barges in with a terrible idea.
“Dennis & Dee Don’t Get Rich” gives Howerton and Olson exactly the pairing that tends to bring out their nastiest work. Dennis and Dee chasing access to wealth quickly becomes an exercise in sibling escalation, with each encouraging the other’s entitlement until they are openly furious that poor people have entered their field of vision.
Howerton can turn a tightened jaw into an entire argument. Olson answers him with the particular Dee expression that says she has identified the stupidest person in the room while remaining unaware it might be her. Together, they operate like two people pouring gasoline into the same bucket and arguing over who gets the match.
Rickety Cricket’s appearance produces another perfect piece of accumulated continuity. When the Gang acts curious about how he became a homeless drug addict, Cricket is stunned. They caused a sizable portion of it. Eighteen seasons of continuity, and somehow the Gang remembers none of the evidence against them.
Five Idiots Versus 2026
“The War on Alcohol” takes one of Season 18’s cleanest premises and lets the Gang destroy it properly. They discover non-alcoholic beer and respond as if somebody has attempted to nationalize Paddy’s Pub. The premise works because drinking has always been built into the show’s behavioral rhythm. Characters enter Paddy’s, grab a beer, form a plan, misunderstand the plan, and make everything worse. Remove the alcohol and the Gang begins questioning the entire architecture of human civilization.
Charlie and Mac’s conversation about factories is especially good. Their conception of industrial labor involves molten material everywhere and workers sitting on steel beams eating lunches from paper bags. They have absorbed decades-old pop-culture imagery and filed it under “how employment works.”
That particular strain of stupidity gives the episode its sharpest social joke. The Gang’s problem with modern life is frequently less ideological than archaeological. They learned how the world worked from old movies, television, advertising, and half-remembered childhood images, then stopped updating the files.
Some familiar Mac material lands with less force. His sexuality remains fertile ground whenever the jokes grow from his need for approval, masculinity, religion, or his baffling self-image. Repeating the same recognition gag gives Rob Mac less to play than the character’s insecurities usually allow.
Elsewhere, “2026: A Virtual Insanity” throws the Gang against homelessness and their reliance on technology. This is classic Sunny construction: locate a recognizable social problem, hand it to people incapable of discussing it responsibly, and let their selfish interpretation become the satire. The writers rarely need Dennis to explain the social thesis. Watching him react to inconvenience usually does the job.
Charlie gets another strong showcase when the Gang undergoes ADHD testing. The story pushes Charlie’s particular form of intelligence toward medical absurdity, raising the possibility that he is somehow a spectacular idiot and an unusual genius occupying the same body. Day attacks the material at speed, stacking Charlie-isms until the distinction between insight and nonsense gets slippery. Charlie Kelly: medical mystery. Philadelphia can bill insurance later.
Stuck in Somebody Else’s Rerun
Season 17 frequently pointed toward current television and celebrity culture. Season 18 keeps glancing backward. Back to School, Gilligan’s Island, and Jamiroquai become major reference points, which makes the Gang’s cultural age part of the season’s comedy. Their worldview has always been outdated. Now their reference library is joining them.
The college episode openly plays with Back to School, positioning Frank in the Rodney Dangerfield slot while Dennis and Dee chase their own fantasies of academic status. DeVito understands exactly how to occupy this material. Frank never enters an institution with the intention of respecting it. He enters looking for weaknesses in the walls.
The homage occasionally feels like the story was constructed backward from the reference. Earlier Sunny episodes could begin with something painfully ordinary, such as trying to leave Philadelphia for a road trip, then discover escalating insanity through character behavior. Here, viewers can sometimes see the reference framework before the Gang has fully vandalized it. “Gilligan’s Island: A Conspiracy Theorist’s Paradise” is far stranger and therefore a better fit.
Charlie and Mac obsess over why Gilligan’s Island failed to reach 100 episodes and why the Professor never successfully repaired the S.S. Minnow. The episode recreates the old sitcom’s costumes, sets, and laugh-track grammar, placing the Gang inside an older television language while their conspiracy logic mutates around them.
The formal joke matters. Charlie and Mac treat a sitcom production choice like suppressed historical evidence. Once they start applying the same reasoning to other conspiracy ideas, including the existence of birds, the episode turns television nostalgia into its own deranged research methodology.
A Jamiroquai concert supplies another generational marker. The joke barely needs explaining. These people are aging, their cultural touchstones are aging, and they remain furious that younger people have continued having culture without consulting Paddy’s Pub. Virtual insanity, indeed.
The Chemistry Outlives the Schemes
The series can survive a weaker premise because the actors know exactly how these characters damage one another. Howerton and Olson remain lethal together. Dennis and Dee pursuing money or academic prestige works because competition immediately replaces cooperation. One sibling making a bad decision functions as permission for the other to make a worse one.
DeVito continues treating Frank’s body like a prop nobody insured. Death, injury, ceremonial dignity, and basic sanitation give him playgrounds rather than restrictions. Mac gets stronger material whenever his parents, sexuality, masculinity, and approval-seeking collide. Rob Mac has spent years finding tiny variations inside a character who could easily have hardened into one repeated joke. Mac wants everyone to witness the version of himself he invented five minutes ago. The Gang refuses to cooperate.
Recurring characters provide their own historical weight. Cricket’s ruined existence has become a running record of the Gang’s collateral damage. The McPoyles return during the Renaissance Faire material, bringing the particular sense that everyone involved should probably have been denied entry at the gate. One moment reportedly pushes Dennis far enough that Charlie questions if they can remain friends. Consider the calibration required here. Charlie Kelly has watched Dennis for decades.
“Mac and Dennis Tear Their ACLs” turns the pursuit of a Christmas-card photo into self-inflicted physical disaster, another example of the series finding catastrophe inside an objective most sitcoms would resolve before the opening credits.
Some Season 18 stories feel built from references before character motivation. Some familiar jokes arrive carrying visible mileage. Then Howerton pauses half a second before responding to Dee, or Day misunderstands a sentence in exactly the wrong direction, and the machinery snaps back into place. Twenty-one years later, Paddy’s Pub still has terrible service, questionable hygiene, and impeccable comic timing.
It’s Always Sunny in Philadelphia Season 18 premieres on FXX and Hulu on August 17, 2026. The long-running sitcom follows a group of self-centered friends who run an unsuccessful Irish pub in South Philadelphia and constantly hatch absurd, morally bankrupt schemes.

The Review
It’s Always Sunny in Philadelphia Season 18
Season 18 still knows the funniest thing about the Gang is how confidently they misunderstand everything. Non-alcoholic beer becomes a culture war, Gilligan’s Island becomes conspiracy evidence, and a college trip becomes another excuse for Dennis, Dee, Mac, Charlie, and Frank to weaponize stupidity. Some nostalgia-heavy plots feel constructed backward from the reference, and familiar Mac and Cricket jokes occasionally scrape old paint. Yet the cast’s timing remains viciously precise, while the darker funeral material proves the show can still find fresh ways to behave terribly. Twenty-one years in, Paddy’s Pub is somehow still open. Terrifying.
PROS
- Razor-sharp ensemble chemistry
- Strong non-alcoholic beer episode
- Inventive Gilligan’s Island experiment
- Dennis and Dee at their worst
- Darker comic streak
CONS
- Some reference-driven plotting
- Repetitive Mac jokes
- Cricket material feels familiar
- Crowded opening episodes
