Sci-fi isn’t all dystopia and disaster; When the Stars Gossip infuses the genre with heartfelt romance and meticulous world-building. The Korean drama invites you aboard a futuristic space station where Commander Eve begins a complex relationship with tourist Gyong-ryong. Not only does it weave romance through a tapestry of intricate space logistics, but it also channels the emotional depth of films like Gravity and The Martian. Smart use of science fiction tropes, from zero-G interplay to the protocols of future space tourism, make it unique among contemporary offerings.

The Institute (MGM+): Stephen King’s Psychic Paranoia

Based on Stephen King’s haunting novel, The Institute delves deep into the ordeal of Luke, a teenager with psychic abilities imprisoned by a shadowy organization. Despite mixed reviews (63% on Rotten Tomatoes), the show’s unsettling blend of governmental conspiracy, supernatural powers, and psychological drama keeps viewers hooked. With a second season planned, there’s the promise of further twisted revelations and deeper dives into King’s dark universe, capturing the mood of his most unsettling works.

The Eternaut (Netflix): Survival Amidst Alien Snowfall

The Eternaut is a faithful adaptation of the iconic graphic novel, centering on Juan Salvo and his band of survivors battling an alien-induced snowfall apocalypse.

Its visual ambition and emotionally charged storytelling have already set expectations sky-high for future seasons, cementing its spot as a must-see for comic book and science fiction fans alike.

Revival (Peacock): Mystery Meets the Macabre

Each episode teases new layers of mystery, satisfying genre fans who crave both eerie atmospherics and convoluted conspiracies.

Murderbot (Apple TV+): Humanity in a SecUnit’s Eyes

Don’t be misled by the name: Murderbot is as much about emotional discovery as it is about android action.

Combining razor wit, action-thriller beats, and a surprising amount of heart, Murderbot exposes the human condition from a synthetic perspective, making it essential viewing for anyone exploring AI ethics or sci-fi comedy-drama hybrids.
