Throughout all of sci-fi, the very best films tend to sway closer to the action genre. Science fiction like Moon offer an introspective look at the very nature of humanity, but the film lacks that element of action audiences generally expect and enjoy in their sci-fi movies and television shows. Fortunately, Hollywood pays attention to what their fans enjoy and hundreds of films and TV shows have been made that easily fit into the sci-fi/action genre.
If your preference leads closer to the "western" style of sci-fi/action, there are television shows like Firefly and its film Serenity. The universe detailed in those examples follow a tyrannical government out to stop the good businesspeople/smugglers just trying to survive in a universe fraught with peril. Lighter fare like Fox's Futurama offer a glimpse at the life of a delivery boy thrust 1,000 years into the future. The series relies heavily on humor and nerd-culture, but still manages to throw some action and peril into the mix. Of course, there are plenty of other great sci-fi action movies and TV shows to check out—and you can find the top choices on the list below.
