HBO Max's science fiction and fantasy shelf is deep enough that it barely counts as one shelf anymore. Dragons and iron thrones sit next to interdimensional cartoon chaos, a run of DC heroism gets equal room next to vampires and doomsday clocks, and one of the most quietly devastating dramas ever made about grief lives right alongside all of it. Here are twelve series worth your time, starting with the ones making news right now and working back through the ones that earned their reputation the slow way.
House of the Dragon is airing new episodes weekly at the moment, with its third season building toward an August finale. Showrunner Ryan Condal has already confirmed the show will wrap after a fourth season, so this run reads as the back half of the story rather than the start of a new open ended chapter. James Norton has joined this season as Ormund Hightower, one more piece of a Targaryen civil war that keeps widening its cast without losing the family at the center of it.
Rick and Morty finally got its eighth season out in 2025, years later than planned after production stalled amid the writers strike. Ten episodes landed weekly on HBO Max, and the show used the gap to keep doing what it does best, swinging from cosmic horror to Jerry's very small, very human humiliations without missing a beat. It remains one of the sharpest adult cartoons going, built for anyone who wants their science fiction with a body count and a punchline.
Game of Thrones just passed fifteen years since its 2011 premiere, and HBO spent this spring marking the anniversary with new footage and retrospectives rather than letting the date pass quietly. That attention makes sense given how much the franchise keeps expanding around it, this very list included, since House of the Dragon carries the same fictional history forward. The original series still holds up as the show that proved fantasy could carry prestige television, and it rewards a revisit now that the wider timeline keeps growing.
Teen Titans Go! has been renewed into a tenth season, making it the longest running DC animated show ever produced. That kind of longevity is easy to overlook because the show plays for laughs rather than lore, but its willingness to needle the rest of the DC catalog, including its more serious siblings on HBO Max, has kept it durable long after most superhero cartoons would have run out of jokes.
The Vampire Diaries hit its fifteenth anniversary with creator Julie Plec looking back on how a Mystic Falls love triangle grew into an entire supernatural franchise. The original series is still the tightest version of that story, moving fast enough that its early seasons rarely feel like setup for what came later. It is the show most responsible for turning the CW's brand of romantic horror into a genre of its own, and it holds up as a complete binge on HBO Max.
Adventure Time wrapped its original run in 2018 after ten seasons, and it remains the rare kids show that adults kept watching for the same reasons kids did, a mix of genuine strangeness and unexpected heart. Its afterlife has only grown since, with the world of Ooo continuing through further spinoff series, proof of how much story Pendleton Ward and his team packed into what looked, at first glance, like a simple premise about a boy and his dog.
Young Justice is a good reminder that persistence works. Cancelled after two seasons on Cartoon Network, it came back years later thanks to a fan campaign that ran the better part of six years, first for DC's own streaming app and eventually for HBO Max. The show earned that comeback by treating its teenage heroes like an actual ensemble, tracking friendships and rivalries across seasons instead of resetting them episode to episode.
True Blood is not getting a sequel any time soon. HBO spent years developing a reboot with original creator Alan Ball attached before quietly shelving it, which leaves the original seven season run as the definitive word on Bon Temps. It is still one of the better arguments for vampire fiction as social commentary, using its small Louisiana town to poke at prejudice and small town politics as much as at bloodsucking, and the whole run streams on HBO Max.
Peacemaker closed out its second season in 2025 with critics considerably warmer on it than general audiences, a split that has followed James Gunn's louder corner of the DC universe before. The show remains one of the better arguments that a self serious superhero universe does not need to be self serious all the time, and John Cena's performance has only gotten more confident with a second season to stretch into on HBO Max.
Superman and Lois ended its run in December 2024 with a finale that jumped more than three decades ahead of its own story, an unusually bold choice for a network Superman show built around small town family life. That last stretch gave the series room to close out threads it had been building since its first season, rather than wrapping up in a rush the way a lot of cancelled dramas do.
Titans closed out its four season run in 2023 with the whole team sitting down for one last dinner together, a quieter note than the fight that preceded it. Across those four seasons the show pushed Dick Grayson and his makeshift family through a grittier, more grown up version of the Titans than television had tried before, and that tonal swing is still what makes it worth starting from season one on HBO Max rather than jumping in partway.
The Leftovers never found a big audience during its original 2014 to 2017 run, but it has been steadily reassessed since as one of the best things HBO has ever made. Damon Lindelof built the show around grief rather than mystery, and that choice, unfashionable at the time, is exactly why critics keep returning to it years later. Of everything on HBO Max in this genre, it rewards patience more than almost anything else.
Start with whichever universe already has your attention, then let it lead you to the next one.
