Season 18 Review

⚠ Spoiler alert Season notes below reveal how the story develops.

In season 18, Charlie, Mac, Dennis, Dee, and Frank are wrapped up in salvaging inheritances from a dead woman, surviving tent encampments and the great inside outside divide between the haves and have nots, withstanding job loss at the hands of workplace automation, embracing a newfound appreciation for neurodivergence, questioning the fabric of society against conspiracy theories, and of course, the biggest elephant in the room, outlasting the public’s pendulum swing against drinking. Not to mention battling nerds, LARPers, and a particularly petulant McPoyle clan at the Renaissance Faire or sportswashing their way back into the good graces of their community by sponsoring a Little League team. All the while trying to maintain order in their personal lives and at Paddy’s, which have become increasingly lawless and erratic.
