10 Nearly Flawless HBO Miniseries You Forgot Existed

You ever scroll through HBO Max for two minutes and realize you’ve forgotten half of what’s in there? Same. Even die-hard TV obsessives (guilty) lose track of how much HBO has churned out over the decades. Sure, the network is synonymous with the big guns—The Sopranos, Game of Thrones, Band of Brothers, yadda yadda—but meanwhile, a whole graveyard of excellent miniseries sits in the shadows, barely remembered by anyone except the most stubborn completists. Sometimes they debuted quietly before streaming took over. Other times, they got overshadowed by something flashier or just got plain lost in the algorithmic void.

Let’s dust off 10 HBO miniseries that deserved a much longer afterlife than the TV gods allowed.

10 Forgotten (But Great) HBO Miniseries

1. The Outsider (2020)
   If you have a complicated relationship with Stephen King adaptations, you’re not alone: there’s either the magic of 'Carrie' or the “What even was that?” energy of ninety percent of the rest. 'The Outsider' decided to zig where others zagged—opting for a tense, slow-burn vibe instead of gross-out shocks. The story starts off like this: Jason Bateman is a beloved Little League coach, suddenly accused of an unbelievably awful murder. The evidence makes no sense, and the show stretches that knot across all ten episodes. Ben Mendelsohn plays the weary, compulsive cop, and Cynthia Erivo steps in halfway as the investigator with almost supernatural vibes—frankly, she got an Emmy nod, and rightfully so. Trouble is, the show premiered just weeks before COVID hit. Even with good reviews, the pandemic swept it straight out of cultural memory.
2. Generation Kill (2008)
   David Simon gets tons of love for The Wire and Treme, but hardly anyone talks about 'Generation Kill,' which is bonkers given it’s probably his bravest project. It’s based on journalist Evan Wright’s book about the 2003 invasion of Iraq, with Wright himself as a character (played by Lee Tergesen). This thing is brutal: filmed on the ground with no comforting music or outsider perspective, just acronyms, war chaos, and a front-row seat to modern military dysfunction. The cast is a who's who of future stars like Alexander Skarsgård (already showing True Blood levels of intensity) and James Ransone, whose character copes with boredom by rapping. It’s sort of like if someone made a Real World but everyone has a machine gun.
3. I’ll Be Gone in the Dark (2020)
   Adapted from Michelle McNamara’s bestselling true-crime book, this six-parter takes on the hunt for the Golden State Killer—the serial predator who haunted California throughout the 70s and 80s. But the twist? It’s just as much about McNamara herself, who sadly died before she finished the book or saw the case solved. Liz Garbus’s doc uses McNamara’s obsession as the emotional core, making it about what following a mystery can steal from you. Came out the same year as 'Tiger King,' and, well, you know which show ate up all the oxygen.
4. We Are Who We Are (2020)
   If you’ve caught Luca Guadagnino’s films ('Call Me By Your Name', 'Challengers', etc.), you know he’s about vibe—every scene is a mood. This eight-part miniseries is set on a US military base in Italy and follows two emotionally messy teens, Fraser (just arrived with his two moms) and Caitlin (wrestling with her own identity). The whole show radiates that incomplete, stressful wash of adolescence—heat-drenched, jumpy edits, weird sexual tension, the works. There’s even a deep (and perfect) Ryuichi Sakamoto needle-drop in there for music nerds.
5. Tell Me You Love Me (2007)
   Before 'Normal People' and 'Fleabag' made TV all about complicated grown-up intimacy, HBO tried it with 'Tell Me You Love Me.' The show follows three sets of couples at various stages, all seeing the same therapist (Jane Alexander, quietly excellent). No plot twists, no real revelations—just the friction of day-to-day married life and unflinching honesty about sex. People freaked out over the realistic sex scenes (there was actually a whole discussion over whether body doubles were used), but under the skin, it just understands how marriages can quietly implode or hang on.
6. The Plot Against America (2020)
   Imagine Charles Lindbergh defeats FDR and somehow the US drifts into facism. Yeah: this show is bleak, but fascinating. Adapted by David Simon and Ed Burns, it centers on a Jewish family in Newark watching the country lose its mind. The performances—Winona Ryder, Zoe Kazan, John Turturro—are all sharp, but it’s the granular detail (radio reports, campaign posters, kitchen conversations) that sells it. It landed during the thick of the Trump years, and everyone sort of reduced it to just-another-political-parable (which is selling it short). Really, it’s about the horror of watching history turn dangerous in your own living room.
7. I May Destroy You (2020)
   Michaela Coel’s pitch-black comedy-drama deserved the world’s attention, but, typical, did not get it. She stars as Arabella, a writer trying to rebuild her life after being drugged and assaulted on a night out in London. Coel wrote, directed, and acted in all 12 episodes, swinging wildly from comedy to horror to the just plain surreal. She didn’t even submit herself for an acting Emmy, but the series nabbed a nod for Outstanding Limited Series. Totally original, totally uncompromising—seriously, if you want something inventively painful and funny, go watch this.
8. Olive Kitteridge (2014)
   Sure, Frances McDormand won the Emmy and all, but most people flat-out missed this four-parter based on Pulitzer-winning fiction. If you love unvarnished character pieces, it’s a treat. McDormand plays Olive, a tough (often difficult), deeply unhappy schoolteacher in Maine, living out a turbulent marriage with Richard Jenkins (every bit as moving as she is). There’s not much plot, just decades of small-town living, grief, and hard-won moments of grace. It’s the antidote for anyone allergic to TV sugarcoating.
9. John Adams (2008)
   If you think HBO’s period dramas are just about dressing up Founding Fathers to sound clever, think again. 'John Adams' gives us Paul Giamatti in full, irascible form as a prickly, self-absorbed, periodically heroic second president of the US. Laura Linney is all patience and wisdom as Abigail. The production budget was a massive $100 million, and it snagged—wait for it—13 Emmys, a miniseries record at the time. Not your grandpa’s hagiography. This is a warts-and-all, sometimes unflattering epic about what leadership looks like up-close.
10. The Night Of (2016)
    Rounding things out: 'The Night Of.' Riz Ahmed plays Naz, a college student who gets sucked into a nightmare after waking up next to a murdered woman—no memory, panic, and every life choice spiraling into disaster. Watching Naz transform from innocent kid to someone barely recognizable by the end is the show’s secret weapon (Ahmed actually won an Emmy for it, deservedly). Even so, for whatever reason, 'The Night Of' never quite joined the permanent HBO canon. It should have.
