Star Wars is also renowned for its creation of the Lightsaber, one of the best weapons ever created, it can be used to deflect blaster bolts, cut things, kill people, seal doors and pwn everything in sight.
Weather you prefer the original Star Wars, and its two sequels with Its Great Story telling aspect, and classic lines like "Its a Trap!", The Prequel's, with the back story, dark tones, and stunning visuals (or just *sigh* Jar Jar Binks), Or, your a Fan of the 2008-2011 installment if Star Wars, The Clone wars, with Ahsoka Tano, the apprentice of the future Dark Lord, Star Wars has something for everyone.
*Side note* Mostly gains attention of "non viewers" By using sexy female aliens, such as Twi'lek's or Togruta's to hook the viewer so he or she can watch the story. Ex. Princess Leia from ep 4-6, Padme Amidala from ep 1-3, Ahsoka Tano, Aayla Secura for the 2008-2011 Clone Wars television series, And Darth Talon, from the Legacy Era.
