The Finest 10 Science Fiction & Fantastical Television of 2025
How would you do if you had unlimited ability? That's a central question explored by all greatest science fiction and fantasy tales. What if you possessed superhuman abilities? Perhaps stumbled upon a revolutionary substance? Or if every single person became wholly committed to your personal happiness? Could you wield such influence for the greater good, or succumb to your own baser instincts?
These series featured herein all explore that very dilemma in unique manners (aside from a single key exclusion). Detailed below is our list of the 10 best seasons of science fiction and fantastical TV from the past year.
10. Spider-Man: Your Friendly Neighborhood
Despite over six decades of stories, the web-slinger is constantly reimagined by fresh creative voices. This series delivers a refreshing look at the hero's formative days, cleverly combining essential source material elements with ideas from the broader Marvel universe to create something that feels both fresh and profoundly compelling.
Rather than being alone or Iron Man as a mentor, this version of Peter Parker develops a complex partnership with the future Green Goblin, who here is merely the CEO of Oscorp. Through their interactions, Peter becomes a true hero, internalizing the signature mantra of power and responsibility.
9. Hazbin Hotel Season 2
Showrunner Vivienne Medrano's audacious adult musical-comedy series, which sprang from a crowdfunded pilot, truly hit its stride in its sophomore installment. Following the game-changing revelations of the first season, the narrative expands considerably, centering on the ambitious media overlord Vox as he seizes command of the situation, sparking a series of ever-more explosive conflicts that naturally culminate in elaborate musical numbers.
While it may lack a single breakout hit quite like the first season's "Loser, Baby," this is due to everything in this season being increasingly ambitious. The fight sequences, personal arcs, and especially the music are collectively more sophisticated. The story moves the main storyline dramatically while providing no shortage of bizarre, wild, and ultimately entertaining fantasy.
8. Daredevil: Born Again
Following the legendary Netflix show, this series had immense shoes to fill. After well-documented production challenges, the final show proves it was worth the wait. The story centers on Matt Murdock once his dual life as Daredevil is exposed, leaving him a target to foes from his past and new threats in a slightly take of his well-known world.
The premiere is a thrilling return to form, evoking the intense tone fans cherished from the original series. While the middle chapters explore some new narrative ground, the first season finishes powerfully, setting fans eagerly anticipating a second season.
7. Common Side Effects
A unexpected 2025 gem, this show is essentially an animated Breaking Bad with the sensibility of a suburban satire. Created by an Adult Swim veteran alongside writer Steve Hely, it tells the saga of a nerdy fungi expert who finds a curative mushroom and soon finds himself hunted by forces including unscrupulous pharmaceutical CEOs to government authorities.
Despite being a parody, the show unfolds with the serious atmosphere of a 1970s conspiracy film. Accentuated by trippy visuals and an unnerving musical soundtrack, the story explores bigger questions about the substance's true capabilities. It's a intelligent, visually striking, and completely gripping first season.
6. Fallout Season 2
This hit series of the popular video game franchise came back with a new batch of episodes that expanded its sprawling lore and expanded its post-apocalyptic world. Although it travels in the direction of the legendary location of New Vegas, the season is not a straight adaptation of that game; rather, it continues to examine themes of control and autonomy.
It expertly balances several narrative threads and points of view, from the protagonist's quest for justice to Maximus's struggle with the ideology of the Brotherhood of Steel. The outcome is a deeply layered and utterly absorbing chapter to the ever-growing wasteland saga.
5. Invincible Season 3
This visceral and heartfelt animated show keeps its powerful momentum in its third outing. The hero faces immense challenges on all fronts: preparing for a looming alien threat, mentoring his young brother, and battling with his shadowy GDA. The story once again includes some of the most brutal action scenes the show has yet produced.
The protagonist's bodily and emotional endurance are repeatedly tested. He must contend with opponents stronger than he is, the aftermath of his actions, and the ethical weight of his decisions. Excellent arcs for key cast members like Cecil Stedman and Rex Splode round out a fantastic installment.
4. Peacemaker Season 2
The director's offbeat superhero series came back with increased importance within the new DC universe, and season 2 delivers on both count. Although it successfully lays foundations for upcoming DCU stories, it primarily tells a resonant and focused {
