List Rules
Vote up your favorite action-packed science fiction shows that have aired on television.

The best science fiction action shows are a perfect storm of futuristic imagination and out-of-this-world excitement. The best sci-fi action series ever shown on television pull you to the edge of your seat like a UFO's tractor beam. If you’ve been looking for the best sci-fi action to add some fun to your TV nights, this list of the best science fiction action series of all time will help you figure out what needs to go into your queue.

The really good sci-fi action shows have our heroes battling aliens, space ships and - of course - each other. All that cool tech and cooler space ships are the perfect props for a fight scene. And, on shows where they're on a new world every episode, like Stargate? That is a fresh setting for action and adventure. From more traditional sci-fi like Battlestar Galactica (either of them) to science fiction-styled superheroes as Legends of Tomorrow, action science fiction shows are unstoppable.

Which shows balance action and sci-fi the best? Vote up the best science fiction action shows and vote down the shows that don't deliver cool fights and a breakneck pace with their technological dream.
