What would you do with infinite power? That's the central question posed by the greatest sci-fi as well as fantastical stories. Imagine if you gained extraordinary powers? Perhaps discovered a miraculous substance? Or if each and every single human was wholly committed to your personal satisfaction? Could you wield that influence for the greater good, or would you succumb to your own baser instincts?

These series featured herein each confront that very dilemma in unique ways (aside from a single notable exclusion). Outlined here is our list of the ten top seasons of sci-fi & fantasy TV from 2025.

10. Your Friendly Neighborhood Spider-Man

Even after more than 60 years of history, the web-slinger is constantly reinterpreted by new talent. Your Friendly Neighborhood Spider-Man delivers a novel perspective at the hero's formative years, cleverly blending classic comic story beats with influences from the broader Marvel universe to craft something that feels both new and deeply compelling.

Instead of operating solo or having Tony Stark as a guide, this version of the hero forges a complex relationship with the future Green Goblin, who in this story is merely the head of Oscorp. Across their dynamic, Peter becomes a true hero, internalizing the iconic mantra of great power and great responsibility.
