There was certainly no lack of television content in the 2010s. With the introduction of Netflix, Hulu, Disney Plus, and every other streaming service out there, there's so much to watch; nobody could see everything good. Because of this, a lot of really interesting and exciting science-fiction series went by the wayside despite being well-made and incredibly entertaining.
To be clear, the shows listed here aren't bad, nor did they lack a dedicated fan base. These underrated sci-fi shows are the ones that simply didn't have enough of a fan base to sustain them. They may have aired a couple of seasons, but without the numbers behind them, many were canceled before their time. Others built up quite a following, but their inclusion in the broader spectrum of pop culture never really manifested.
