These series listed herein each explore this dilemma in various ways (aside from one notable exclusion). Detailed below is a countdown of the 10 top installments of science fiction and fantastical TV from the past year.

10. Spider-Man: Your Friendly Neighborhood

Despite more than six decades of stories, the web-slinger remains reinvented by fresh creative voices.

9. Hazbin Hotel Season 2

Showrunner Vivienne Medrano's boldly transgressive adult musical-comedy series, which originated as a crowdfunded pilot, fully found its footing in its sophomore season.
