A really good action television series catches us up in its spell and shows like The Blacklist have kept us on the edge of our seats for years, though newer shows such as The Rookie are just as action-packed. Superhero shows and comic book TV series are both big parts of the best action series in 2021, and that of course includes The Boys and CW Arrowverse series like The Flash and Batwoman. Other great action series airing new episodes in 2021 include action sci-fi shows like The Expanse and the Spanish series Money Heist on Netflix.
