HBO has given us some of the most iconic shows in television history—The Sopranos, The Wire, Sex and the City. But for every legendary hit, there are a handful of series that arrived, wowed audiences, and then quietly slipped off the radar. Whether due to short runs, niche appeal, or simply being ahead of their time, these forgotten HBO shows are perfect from start to finish and deserve a second look.
Hung (2009–2011)
Thomas Jane stars as Ray Drecker, a high school sports coach who, after a house fire leaves him broke, turns to an unconventional side hustle: prostitution. With his above-average endowment, Ray—with help from his friend Tanya (Jane Adams)—launches a secret business called Happiness Consultants. The late Anne Heche plays his ex-wife, and Stephen Amell joins in season three as a younger rival. This comedy-drama flips the typical gender script, delivering laughs without being crass, and remains a refreshingly bold take on desperation and reinvention.
The Leftovers (2014–2017)
Justin Theroux leads this supernatural post-apocalyptic drama about the Sudden Departure, where two percent of the world's population vanishes. As police chief Kevin Garvey, Theroux navigates a fractured society, cults like the one led by the self-proclaimed messiah Holy Wayne (Paterson Joseph), and personal loss. Though initially dark, the series shifts tone in later seasons, earning a devoted cult following. It's a masterclass in storytelling and emotional depth, often overlooked in HBO's pantheon.
Rome (2005–2007)
This historical epic follows soldiers Lucius Vorenus (Kevin McKidd) and Titus Pullo (Ray Stevenson) during Rome's transition from republic to empire. A co-production with the UK and Italy, Rome boasted massive sets and a stellar cast, earning awards and high ratings. But its high production costs cut it short after two seasons, despite plans for five. Today, it feels like a precursor to Game of Thrones, and would likely have thrived in today's streaming landscape.

Landscapers (2021)
This four-episode true crime black comedy stars Olivia Colman and David Thewlis as Susan and Christopher Edwards, a mild-mannered couple who murder Susan's parents and bury them in the garden. Based on real events, the miniseries boasts a 98% Rotten Tomatoes score, yet remains one of Colman's lesser-known projects. It's a bizarre, binge-worthy tale that proves fact can be stranger—and more compelling—than fiction.
Bored to Death (2009–2011)
Jason Schwartzman plays Jonathan Ames, a struggling writer who moonlights as a hilariously inept private investigator. With Zach Galifianakis as his best friend and Ted Danson as his editor, this comedy aired after Curb Your Enthusiasm and earned critical praise. Fans even campaigned for a revival after its three-season run. It's a witty, star-studded series that still holds up today.
Enlightened (2011–2013)
Laura Dern stars as Amy Jellicoe, a corporate executive who suffers a public breakdown and embarks on a journey of self-improvement. Created by Mike White and Dern, this dramedy explores themes of redemption and authenticity with sharp writing and a standout performance from Dern. Though short-lived, it's a hidden gem that resonates more with each rewatch.
These shows prove that perfection doesn't always mean popularity. Whether you're into crime, comedy, or historical drama, these forgotten HBO series are worth rediscovering.
