These sci-fi series all have impressive Rotten Tomatoes ratings of 90% or even higher. Although there are some fantastic shows from this endlessly fascinating genre, not all of them hold this record. Even Lost , which is one of television's most popular and gripping sci-fi stories, only has 86%, and Netflix's terrifying anthology series Black Mirror has 83%.
In order to truly impress fans, a sci-fi show needs to create a thrilling and scary world with advanced technology or mysterious creatures, and the world-building should feel logical, not cheesy. Too often, series become bogged down with confusing subplots, and there's no satisfying payoff.
These sci-fi series have solid characters and incredible storytelling, and they've earned their Rotten Tomatoes ratings and positive
