Star wars has probably the best storyline of any series of movies out there. Most people think it's about Anakin's/Darth Vader's rise, fall, and redemption. It's your classic good vs evil, light vs dark movie. Also, if you're that type, you can read deeper into star wars movies (i.e. religious undertones)... yes I ama star wars nerd... Yes, I am 19 and have an obi wan lightsaber (hard to get) from episode II.
